I'm a developer and am always looking for the next big platform to develop for. This sounds absolutely perfect. I definitely agree though that if there is no text editor local to the machine I wonder how well it could be used for development, but overall I think it would be interesting to test the device.
I'm a heavy Google services user for work & personal (as i'm sure most people here are), and I start commuting 2hrs each way to work in a month, so something like this would've been perfect for the commute. I'd happily spend that time testing the laptop and taking part in feedback. Ah well.
