My first thought: "Google OS, great! Go google! Wait, haven't googles products got steadily less and less stable and good as the company has expanded? oh well..." Then I realize this is another OS on an already shattered market (PC/laptop). Of course it's based upon Linux but it doesn't support a lot of heavy features. Basically it's made to boot an Internet browser and nothing else. This is, of course, Google's stratagem and has been from the start. And I see their point, web apps are steadily taking over functions I used desktop apps for earlier.
But there is a long way to go, web apps are just not responsive enough for smaller tasks, I use notepad, and Things. Programs that are snappy. I haven't seen anything web based that comes close to them in responsiveness.
Maybe HTML 5 can speed things along.
