+ Trevor Gilbert I agree you can't write a review based on a hypothetical but the review felt like you dismissed some of the potential of the OS. I'm an iOS user myself but I also use lots of Google services and I can see that for a good part of the tech illiterate portion of the population these would make good machines.
I think Chrome OS is a very tough sell for the vast bulk of people whose minimal computing needs are probably better met by a tablet. If they're going to have to undergo the paradigm shift of a whole new OS from their current laptop/desktop, I'd have a hard time convincing them that they shouldn't just jump two steps ahead instead.
For folks who do need a more dedicated machine, I think it really only speaks to those whose online lives are already tightly integrated with google services. That's a lot of people, but it's not everybody. It also suffers from the web-as-platform problem of there not being web-based equivalents of everything people need to do (yet).
