Palm Pre Hardware Overview and Impressions
5 p* F# V2 L3 N. w- h
By: Kris Keilhack Photography by Ryan Kairer January 10, 2009
尺寸和外形特性
Pre 很小.关闭滑盖后比TREO PRO和CENTRO都小.比我预期的还小一些,尺寸上象一个从MOTO的Pebble系列中脱胎而出的小一号的HTC TOICH..Palm PRE的更紧凑圆滑一些.

机器外表光滑,所以很容易看起来很脏(所有污迹在反光下都比较明显),机器周边浑圆的边角和界面让人感觉很衬手舒适,我有机会拿了一下,但是PALM看得很紧,谁都不能长时间握在手上(所以没办法更深地体会手持的感觉)
我无法描述这种顺滑感但是我真的觉得它顺畅快捷,没有发现原来的PALM TT系列是那种滑盖结构的低劣,我看到机器一直在展示界面中,滑盖/键盘没有因意外误动作而猛然合上过(在TT3中经常出现这种问题)
当滑盖打开.显露出来的背面是一个光洁的镜面,那个位置通常是被忽略的,PALM在那里装了一个大的抛光后的镜面,加大了拍照时用的镜子或是给女士们化妆时使用.

就象一些经常使用手机的人希望的"如在耳中"的感觉,PRE显得握持和使用非常舒服,尤其是与G1的"弯曲"外形相比.我感觉这款手机滑开或关闭时使用都很符合"电话人体工程学"的理念,尽管PALM说如果打开滑盖使用键盘的话,当然距离稍稍远一点更顺手
跟大家推测的不同,前面的那个按钮不是轨迹球,那只是一个简单的HOME按键,与iPhone的那个Home键类似,另外比较舒适的一点是,那个按钮透着柔和的白光(应该是半透明背面有光的那种效果),当邻近的手势区有明确的动作时

Keyboard
Palm Pre的键盘看起来庄重雅致,向Palm致敬,他们开发了一个非方屏机上用的"真正的"键盘,在一台这样圆滑外形的设备上有这样的一个键盘真是让人高兴的事情

抛开原来的一些不实报道,我很高兴地告诉大家,键盘中除空格以外几乎所有的都有背光. 背光是亮白银,只照亮字符本身而不是象CENTRO那样整个按键都是亮的..说到CENTRO,PALM PRE好象没有使用采用Centro那样的单面平键盘设计,而是轻微地有些圆,象个球,有鲜明的标记,数字和Shift钮是橙色的
重要注释:PALM抛开他们原来的思路,重新规划测量了一些按键:

@ 键放在空格键边上,与0一起.Palm的解释是近年来@比以往越来越多地使用
& U5 N) Y1 e+ r) t, }$ O. B
原来右下角的菜单 "menu" 键换成了输入符号用的SYM钮
& ^$ o' [& \: T, z/ U* X
挨着空格的ALT现在定义为句号(.) --(就是一个点,小数点那种) `. F. s9 ^" u, V6 g, j, d" ^

我近距离观察但没真正拿在手上,看起来键盘总面积及间距都比比Centro和Treo Pro要大一些,但是不如经典的Treo 700系列那么大

. Thankfully, the vertical smile shape is retained but it's not as pronounced as on earlier models.
看起来下部的一些空白处是无用的但是考虑到滑盖与机身吻合的情况，这样的空白区域看起来是必要的

Screen & Sensors

Palm把屏幕描述为“丰富的24位色彩”和3.1"大尺寸屏幕.它采用电容式触屏科技，不象以往palm过去12年里的各款产品上的透反触屏
palm的用户期待大屏幕智能电话已经多年（不要求系统），这次他们没有失望

我个人很高兴看到一个更大的物理尺寸更高分辨率的屏幕,Palm终于把他们5年前的TT3屏幕用在现的在机器上,跟APPLE的iphone保持同步.PRE的屏幕显示更丰富,颜色更细腻鲜明,饱和度更好,(在更好的黑色背景下),
在Pre上播放的几段视频没有出现卡的情况(很顺畅),画面轻松充满整个屏幕.对于将来的WebOS设备,我喜欢能有更大的屏幕和更高的分辨率.但 320x480的屏幕已经是我们在 320x320方屏之后期待了很久很久的

在屏幕上角上有一个环境亮度感应器,还有一个接近感应器在通话时可以关闭屏幕以节约电力并避免耳朵触到屏幕上的按钮,
在有过几次令人发狂的使用黑莓Storm的经历之后,我为Pre的重力感应器可以很快速地改变设备的方向舒了口气
在重力感应器和OS配合下有一个很好玩的应用,Palm的员工向我演示了照片程序,Ryan和我与Palm员工隔着桌子站在对面,他说"看看我朋友的这张照片"并拿起Pre.留意PRE从身体较低的位置拿到手上,经过一个向下的手势(就象他把PRE递到我们手上一样),这时PRE处于一个顶部朝下,键盘部分指向人的位置,重力感应器马上感应到这个位置变化,并自动调整屏幕以使我们能够以正确的角度看到照片,WEBOS正确地预测了动作并旋转图片(沿X轴方向)使其正确显示.,当他把Pre转回朝向他自己的时候,感应器又重新调整图片到原来的角度,对我来说中,这是一个非常让人高兴的功能,你可以很轻松地把照片展示给家人看又不必非把机器交在他手上并担心他们可能搞坏你的宝贝(这可能是很多数码发烧友买机初期的心理,即使是家人,也不放心把机器交在他们手上把玩)

MicroUSB and Storage Memory
装在机器侧面的 Micro USB接口由一小块塑料盖保护着,这机器拥有全速USB2.0 接口,最大传输速度可以达到480Mbps. 这个接口可以用来充电,可以把PRE用作PC机的Modem,也可以允许访问是PRE内部把PRE当作一个外接存储器,标准的内置存储究竟是8GB,用户可用大概7.4G.
目前的架构下,机器上没有存储卡槽,就象老PALM一直在原来PalmOS4时代的m505一样,我个人认为,这是Pre上最大的遗憾
Palm展台上的人告诉我"8G对于所有的人来说已经很大了,SDHC目前价格很高而最高也才能到8GB"

这是在体积上和让步和给用户更多价值,他们不用再去买昂贵的扩展卡用在自己的新设备上,我个人而更希望PALM能象RIM那样至少设备里内置1GB可加密存储究竟并提供一个Micro SDHC插槽,目前市面上已经出现了16GB的MicroSDHC卡而且32GB的也将出现.8GB对于一些多媒体应用来说太小了点,尤其在Pre的大屏/立体声耳机和高性能的CPU/芯片组配置下.
我在某个晚上曾经跟SD卡协议企业中的一个成员聊过新的SDXC标准的情况,他们预计今年秋季将会有64GB的扩展卡上市,将来最高容量可能高达2TB.对于PALM来说,从2001年的m500系列机器起,早期的机器支持SD/MMC卡,取消扩展存储卡支持让我很不爽(感觉PALM把Apple对存储卡的恶劣态度也沿袭了一些.)

Battery
Palm确认目前Pre的电池是1200mAh,PALM宣称电池是可换的,我们可以通过图片证明这一点,看起来与Centro/800W的电池设计略有不同,Palm的人员说PRE可以用其他设备的电池但是PALM并没有确认或

, a Palm rep did state that the Pre could share those devices' batteries but it was not endorsed or recommended. While 1200mAh is certain to send chills down users' spines, we need to wait for Palm to make an official statement on battery life, as they were essentially offering 'no comment' at the show.

Pre Performance
The Pre's innards are comprised of the cutting-edge TI OMAP 3430, a very nice integrated CPU whose specs I will not bore you with here. In short, I remain absolutely blown away by the device's performance. Nearly no lag at all, and near-instantaneous screen transitions and redraws were seen all around, everything has a very snappy and fluid feel to it. And the capabilities of the Pre are just the tip of the iceberg, based on the stunning feature set available to the TI chipset.
After over four years of battling with the inherent NVFS lag of various Palm OS devices, I finally have nothing to complain about based on what I‘ve seen so far. This thing is honestly Tungsten T3/TC fast, folks, even with a heckuva eye candy festival going on.

Miscellaneous hardware observations
Thankfully many of the traditional Treo cues remain on the Pre. The top-mounted ring/mute switch, while slightly downsized, is present and handy as ever. The volume up/down buttons are still on the left side of the phone but an unfortunate casualty of the new form-factor is the loss of the shortcut/multifunction button found on previous Palms below the volume keys. I'm also glad to report that the 3.5mm stereo headset jack found on the Treo Pro was not a one-off decision and appears here to much rejoicing. This was a feature heavily touted by Colligan onstage yesterday.

The preliminary Palm Pre retail packaging lists a microUSB sync/charge cable in the box alongside an AC adapter and a stereo headset. As you likely know already, a few stalwart features of every previous Palm device have been jettisoned in the transition to tis new era of hardware and software: the stylus, IR port, and hard application buttons and directional keys found on every device since the original Pilot are gone, in addition to the removable memory card slot and programmable side button discussed above.
The back battery cover is replaceable and will require replacement if the optional and very cool Palm Touchstone inductive desktop charger accessory is used. I did not see a Pre being charged, so I cannot comment if there is a charge/alert notification LED built in the illuminated button area. I also did not notice a reset button under the battery door but I would assume that is just handled via a battery removal cycle. Given the superb stability of the devices we witnessed, hopefully this is a moot point.

Build Quality

Please note that these comments are only from close examination of a brief fondling of one of the Pre-Pre Production device Palm is using here. Build quality in general seems exemplary and the slider makes the action of the old Zire 71 and the T|T series looks like shoddy stuff.
One fantastic nod to Palm's traditional attention to detail is evidenced by the mirrored back panel on the rear of the unit that is exposed when the keyboard is pulled down. This wide reflective area has a nicely embossed Sprint logo and also serves as a fantastic way to frame yourself for self-portrait photos. Simple, classic and elegant and a nice touch that is "simply Palm".
Continuing alongside the rear body of the Pre reveals a small 3.1 megapixel camera lens with a small LED assist lamp. Palm is touting this camera as offering "extended depth of field" capabilities via an onboard DSP but it remains to be seen how this feature can actually benefit the typical sub-par mobile phone image capture experience. Palm is saying the camera is for pictures only at this point and they won't say whether video recording is planned.
This wraps up about every aspect of the device's hardware and form factor, based on many discussions, interviews, spec sheets and hands-on observations that I've been able to make over the past few days here at CES. We are going to try and meet up with Palm once more to field a few questions and will then be well-equipped to develop a thorough overview of the device's main attractions of the fantastic new OS and UI.

Palm Pre Hardware Overview and Impressions
: w1 t& G# E0 e, g7 X+ W+ U2 ], F
By: Kris Keilhack Photography by Ryan Kairer January 10, 2009
Size & Formfactor
The Pre is small. Smaller than even the Treo Pro and even smaller than a Centro when closed. In fact, it's quite a bit smaller than I was anticipating it to be. Size-wise it looks to be a slightly reduced-size version of the original HTC Touch with styling cues taken from Motorola's "Pebble" dumbphone series. A Palm rep I spoke with compared the exterior to a smooth, rounded river rock.

The device has a glossy exterior that is unfortunately quite a smudge reflector. The gently rounded edges are a nice touch and befitting with the "organic" feel of the device and its UI. I did briefly touch the device but all of the Palm reps were pretty protective and were not allowing people to did not hold it in hand for very long.
I cannot comment on the slider feel but the action of the slider that I observed repeatedly seemed smooth and quick, without the coarseness found on Palm's older Tungsten T series sliders. I watched the device being demonstrated in landscape mode and the keyboard never snapped shut by accident (a frequent problem I used to experience on my T|T3).
When the slider is extended the back of the exposed display ares hides a smooth reflective mirror surface. On what is usually a neglected area, Palm has thoughtfully put a large mirror finish surface that doubles as an extra large self portrait camera mirror or a convenient place for the ladies touch up on makeup.

As someone who uses their device frequently for conventional "on the ear" telephone purposes, the pre appears to be extremely comfortable to hold and use, what with its angled with the HTC G1-inspired "bend" when the slider is extended. I am pleased to report that the phone can be used for telephony with the slider open or closed, though the Palm reps indicated it's far more comfortable to use with the keyboard extended, obviously.
The front-mounted button is not a trackball, as has been speculated by some. It is a simple click-action multifunction "home" button analogous to the iPhone's central button. In another nice nod to usability, the button itself illuminates with a soft white light, as does the areas adjacent to it in the "gesture" area when certain actions are performed.
Keyboard
The Palm Pre's keyboard looks solid and elegant. Hats off to Palm for engineering a "real" keyboard alongside a non-square screen form-factor. It's quite a pleasant surprise to find on a device with such sleek and tidy dimensions.

Despite some earlier reports from elsewhere to the contrary, I am glad to report that the keyboard is almost entirely backlit aside from the spacebar. The color is a bright clear white with the letters lighting up and not the full keys as is common on the Centro. Speaking of the Centro, this device doesn't appear to use its single sheet keyboard design. The keys appear to be slightly raised and rounded, almost bulbous, and have nicely contrasting orange labels on the numeric keys and the shift button.
Worth noting, particularly due to the fact that Palm went out of their way to explain this to us, is that some buttons have been remapped:

ALT, next to the spacebar, is now a dedicated period (.) key

From my close-but-not-hands-on scrutiny, the keys themselves are a little roomier than the Centro and Treo Pro but are not as spaced apart as the classic 700-series Treos. Thankfully, the vertical smile shape is retained but it's not as pronounced as on earlier models. There does seem to be a tiny bit of unused space below the bottom row of keys but this seems to be necessary to permit the slider to merge into the main body.

Screen & Sensors
Palm bills this LCD as possessing "rich 24-bit color" and measuring 3.1" diagonal in size. It uses capacitive touchscreen technology, unlike the resistive touchscreen found on every prior Palm device over the past twelve years. Regardless of OS, a Palm smartphone with a large portrait-oriented screen has been eagerly awaited for years and this one does not disappoint.
While I'd personally like to have seen a physically larger screen sporting a few more pixels, Palm is now at least on par with their five-year old Tungsten T3 screen as well as Apple's iPhone. Pre's LCD displayed fantastically rich, vibrant colors with good saturation and nice black levels. A few windscreen videos played back on the Pre were devoid of any stutter or choppiness, and the fast action filled the screen from edge to edge. In future WebOS devices, I'd like to see a physically larger screen with more pixels, but at 320x480 is a solid step above the 320x320 squares we've been saddled with for far too long.

An ambient light sensor is located on the front corner of the screen bezel, as is a proximity sensor to turn off the touchscreen while on a call to prevent battery drain and the dreaded "ear dial" phenomenon. After several maddening experiences with the BlackBerry Storm, I breathed a sigh of relief to see the Pre's accelerometer responding very quickly to changes in device orientation.
One minor but fantastic use of the elegant integration between Accelerometer and OS in the Pre was shown to me by a Palm staffer using the photo app. Ryan and I were standing on the opposite side of the desk from the Palm rep . He said "Check out this picture of my friend" and handed the Pre to use, gripping it by the lower body area and turning his hand in a downward gesture as he "handed" us the Pre. So the Pre was at this point facing us with its top panel facing down and its keyboard "bottom" facing the Palm rep. The accelerometer immediately recognized the movement and inverted the picture so that we could see its proper orientation. In essence, WebOS anticipated the action and inverted the image on the X axis so that we could view the photo in its proper orientation. When he brought the Pre back towards him, the accelerometer flipped the image again and restored it to its normal orientation. To me, this was an absolutely stunning demonstration that could come in very handy for impromptu presentations and letting family members look at a photo without the fear of them handling your device and "messing something up".
MicroUSB and Storage Memory
The side-mounted Micro USB port is covered by a small plastic flap. The device features full-speed USB 2.0 connectivity with its maximum theoretical data rate of 480Mbps. The port can be used for trickle charging as well as for modem tethering to a computer. The port also provides access to the Pre's sole means of data storage. 8GB of fixed internal flash memory is standard, of which approximately 7.4gb are available for user storage.
In its current form, there is definitely no kind of removable memory card slot, despite Palm's legacy of providing expansion memory since the m505 handheld and the days of Palm OS 4. In my opinion, this is the Pre's single greatest drawback. A Palm representative told me that (I am paraphrasing his words here) "8GB is plenty of storage for anyone, especially since SDHC cards are really expensive and just now hitting 8GB capacities".

This regrettable omission was made for both size concessions as well as to give the user more value and convenience, as they would not have to rush out to purchase an "expensive" flash card to use in their new devices. I personally would rather have seen Palm take a cue from RIM's latest devices and have 1GB of encrypt-able storage space onboard alongside the traditional microSDHC slot.
With microSDHC readily and affordably available now in 16GB capacities and 32GB cards hitting the market soon, 8GB is too little for any serious multimedia applications, especially given the Pre's phenomenal screen, stereo headphone jack and impressively performing CPU and chipset.
I spent some time talking to the staff at the SD Card Association booth the other night about the new SDXC spec. They are expecting to launch the format this fall with an initial capacity of 64GB with future cards going all the way up to 2TB. For Palm, an early supporter of the SD/MMC standard ever since 2001 with the m500 line, retreating away from the expandability and flexibility of removable storage cards strikes me as a very ominous sign of aping Apple's unfriendly attitude towards flash memory cards.
Battery
Palm has confirmed that the Pre's stock battery offers a 1200mAh capacity. Palm is really trumpeting the fact that it is removable and we've got the pics to prove it. While it appeared slightly different than the Centro/800w battery design, a Palm rep did state that the Pre could share those devices' batteries but it was not endorsed or recommended. While 1200mAh is certain to send chills down users' spines, we need to wait for Palm to make an official statement on battery life, as they were essentially offering 'no comment' at the show.
