Mine came in while I was gone on vacation last week. I just powered it on last night, and have been loading software on it today. I ran it on battery only during that time, while doing lots of downloads, installs, and with wifi active. It got 6.5 hours of battery life with all that going on! Wow.
I have relatively small hands for a guy, so the keyboard is fine for me. If you have large hands, you may have a problem. I also wish that more fit on the screen (it's only 1024x600), but that comes with the small size, I guess.
Other than that, I really like this thing so far. I do software development for a living. While I intend to only use it for travel & browsing, I have full development tools loaded. It's a bit slower than my desktop, but it's definitely a real computer capable of doing real work. And in such a small package for such a small price. Two thumbs up.
