I believe I read that the Chrome OS would only allow web browsing. No applications. No downloads from the web. To me, this just didn't sound useful, though I guess it might be for, say, a school setting. No viruses ;-) Maybe Chrome has changed - I hope so.

I think Android is the better netbook OS - but they really, really need to open Google Market! And make Google Market better. I've read some criticisms of it being hard to navigate, especially compared to Apple.
