LOL, those things are still around?
I never really understood the point of them. I put Google's OS attempts on the same plane as Microsoft's search adventures. Too little, too late and way off the mark.
To me it's not even about the price, I wouldn't get one even if it was $50 'cause if that was so the hardware would be crap and useless. If you want to exist in Web realm, there's Android/Apple/soon Win8 tablets; pricier - sure, but they're neat and light and mostly right on as far as features/capabilities/utility. For professionals, I don't know anyone that uses their laptops simply to store documents; there's always one or two at least, "special" apps that they use for work.
And even Google's aspirations on creating a unified, maintenance free, up-to-date OS would fall flat eventually if Android is any indication of things to come. The fragmentation is horrendous so from the development standpoint it is a one big patch-happy cock-up. Similar to Linux; great idea, great dev base and all that but Jesus tap-dancing Christ, 2 million versions, distributions, compile-this, aptget-that and most just give up on that idea well before they get started.
And then, if you're hell bent on using Google Apps (really?) why not just get a lappy of your choice and use them. I bought my 11-yo a 10" Asus netbook for 350 bucks. The device is fantastic, does everything that she needs and then some, so why the hell would I spend 500 on a glorified web browser. And for that matter, why would I spend anything on a glorified web browser?
If Google did not already have the Android platform and the world was 100% covered with affordable, high-speed internet connectivity this thing could maybe (maybe) have some legs to stand on. As it is, it's redundant at best and just plain stupid more likely.
