I really want to try one of these, but I can't lie to Google. I don't use the Web for anything. I listen to music with xmms2 on the command-line. I write in Emacs. I read my email in Emacs. I download TV shows from Usenet.
I realized that Emacs is the Chrome OS, except with 25 years of libraries and applications to show for it.
I use the web for visiting websites, but that's only a very small part of my day. Most everything I do for fun or socialization or for creative purposes I do without the web. I may publish my stuff to the web, but it's a medium, not a tool. A painter wouldn't say he spends a lot of time working with magazines, even if most people know his paintings from one.
Anyway, I'm not criticizing the idea of Chrome OS. Like I said, Chrome is basically a pretty Emacs, which is a great environment. But it won't work for me today.
(Would I buy a Chrome OS tablet, just for reading random crap on the web? You bet! But I wouldn't commit to using one as my primary computer, because I wouldn't be able to do anything I want to do.)
Why do you assume Google only wants testers who already use the web for every application? They may seek feedback on the transition process, which many potential customers face. That is, unless this is targeted squarely at children.
