Why do you bother giving high expectations to Google Chrome OS? It's a NETBOOK OS. It's a glorified mobile OS on steroids and crack for fucks sake. (A mobile phone runs on 500-600 MHz, a netbook runs on 1.6 GHz) In that sense, you should be comparing it to Windows 95 or 98, not XP or anything higher.
Because aside from Apple and Microsoft, only Google has enough resources push their OS into the market. I'm discounting other Linux variants here not because they're "insignificant" but because most are not backed up by big companies (I can think of only two atm, Red Hat and Ubuntu)
I believe Ubuntu is backed slightly by Dell and by Canonical. But the latter isn't big and Dell is "Uber Ghey".
Google doesn't need to push. It enjoys a nice fanbase. Just showing chrome around was enough for people to go, "Hey, that's cool, let's try it.". The only difference is that it isn't a leech to consumers like Apple.
In past experience, Google relies heavily on word of mouth for getting their products and programs and other things across. People like Google, and go to Google. Not the other way around. Bing's start (dunno what it is at now though) was like the big greasy man in the candy van without the molestation. "Come to me my precious... you will get cookie..."
I seriously doubt the Google OS will need to be pushed. More along the lines it will have special edition netbook ones to promote itself and then they'll make a very pretty picture guide to "installing Google OS on a netbook". Seriously, if you want to laugh at a netbook, why not laugh at the $600 designer edition Vivienne Tam netbook?
And AFAIK, Google refuses to "finish" many things. Everything is in Beta all the time. Reminds me of Yakitate Japan. Everything is a number till you get pro... then it JA-PAN time bitches!
Several of their services just came out of Beta. Gmail, Google Apps.
If they want to compete, they better be up to snuff. And my guess is they'll be patching that OS as much, if not more than MS.
They've been doing that with Chrome if I'm not mistaken. The updater constantly runs in the background.
Well, I guess those ones can't really be improved much more. Seriously though, I like the shift/ctrl selection of mail. FUCK HOTMAIL FOR TAKING THAT SHIT OUT AND MAKING ME SELECT SHIT ONE AT A TIME.
I think they're just adding functions in Chrome. One of the biggest critiques that it wasn't able to do certain things (when it was first released) was the reason for its original hatin'.
