I think that the Google OS will be great even if I only boot to it occasionally. If it really only takes a few seconds to boot, it will be useful to use when on the road or when I just want to check email.<p>It's a little like using Chrome instead of Firefox. I use Chrome when I actually want to use the web like a normal person, but when I want to do real work and development, I use Firefox because it is so much more powerful (WebDeveloper, Firebug, TamperData, etc).
