> What use case does ChromeOS solve that Android doesn't solve? Printing. Browsing the web and writing long emails like a normal user, rather than like a tablet user: no weird issues with mouseover, fully-functional built-in Flash, etc, etc. There are lots of differences between the web experience offered by Android and the web experience offered by Chrome OS. Also, normal people won't have to make a decision in a store about picking "Android" vs "Chrome OS". It's more and more likely that people will pick from the limited few options in the store, and maybe try it out before buying it. If a store sells laptops and some run Windows, some Mac OS X and some Chrome OS, then Chrome OS will be a serious competitor at least in the netbook form-factor. Tablets are often sold in different parts of a store, or at least together in a different display. You'll see people picking between iPads and Andriod tablets. I doubt that normal stores would display Chrome OS tablets in the same area (but I could be wrong).
