Summary: This is just an excellent laptop. Nice balance between performance and power-saving. The keyboard is wonderful, the screen isn't too glossy, system feels responsive, doesn't get very hot. Some say the Edge isn't a true Thinkpad, but I've got no complaints so far. It's also a great choice for running Linux: the hardware is all well-supported (go for the Intel wireless). An ideal machine for just about any task short of intense gaming/video editing.
Pros: Comfortable Keyboard, Lightweight, Long Battery Life, Quality Display
Summary: You basically pay for what you get. It is a very lightweight machine, but there are trade-offs. The battery does not last very long, so far only 2.5ish hours with wi-fi on and screen brightness at a low level. It also runs a little hot, with the fan turning on frequently. If you only need something for web/email/word processing, then this should be good enough for you. If not, I would recommend going to the next step up.
Summary: This is an excellent buy. The keyboard layout and feel is excellent, the screen looks great, and it's extremely portable. Runs streaming music and HD video without a problem. The only "con" I can find is that it comes with a 4-cell battery, which is good for about 3 hours of moderate use (most computers in this class come with a 6-cell battery). Nonetheless, I still prefer this notebook over any other in this price range.
Summary: I owned a T43 prior to the Edge, and when the T43 died, I scrambled to replace it. Luckily the Edge had just arrived on the scene. Six months later I'm still in love with this lightweight, versatile and surprisingly fast notebook. The obvious +'s are its slim form factor, PHENOMENAL keyboard (how do they do it time and again?), crisp display, large touchpad, trackpad, powered USB and integrated webcam.
Summary: My ThinkPad x61 got dropped, hard. A replacement would have been $1,200+. This was $650+. It's a good general purpose business laptop. Heavier than I would have liked, but ok for the price. Assembly defects and battery misbehavior on opening the box. The former I was able to fix and the latter seemd to fix itself. T'was not confidence inspiring, but seems to work well now.
Summary: I researched comparable models for months with the SU7300 processor. I was not convinced that it would be fast enough, but it handles all of my needs very well. I have had Chrome, Evernote, I-Tunes, Quicken, Picasa, and Pandora Desktop open at the same time without a hitch. I've tested 1080 video, and it is as smooth as butter. I've also watched a full Amazon VOD movie w/ the HDMI cable connected to my TV without a hitch.
