Mine has an issue and an easy fix is just plug in someone else's battery and turn it on and off. I would give someone $5 or something if they have one near me.
I've been using my chrometop as my main web device for 5 months now and have found a few other great uses for it. Primarily, my elementary aged children use it and Google Docs to compose all of their typed assignments. It is so much better than worrying about files on different machines. The reason why the CR-48 is ideal is because I pretty much never have to worry about the thing breaking down or managing programs. Having a second chrometop would let me use mine while the kids use theirs....
The only problem is that it's 1500 miles away at my parents house...
I like the light feel of it and it could definitely replace my netbook, but doesn't really hold up that well compared to my main laptop. The video playback leaves a bit to be desired, but overall I think it's a step in the right direction.
I didn't even sign up on the first round, I signed up in December, seem to have got it rather quickly. Maybe it is because I've had GMail since early 2004 and have had quite a number of Android devices as well. Like another commenter, I also have a Galaxy S (Vibrant). I look forward to testing out the tethering in Froyo with this once the 100mb 3G runs out on the go.
After using it for an evening and doing all of my surfing on it I can say I like it a lot. Its light, I can carry it around really easily, it has good battery life, it doesn't get hot, and well my only complaint so far is it doesn't quite have the horsepower for higher quality web video, but really I personally don't look at a lot of that anyway.
I haven't used mine that much since that first week I had it, mainly because I (continue to) find the trackpad so difficult to use.
I think as the Chrome apps are developed and refined, the CR-48 becomes more and more useful, but without any access to any files locally, I can't see it completely replacing any of my other systems.
Based on their knowledge base they are not currently supporting this feature. This is a huge problem for a laptop without a file system.
