Sorry, I disagree
Well, I've been working as a software designer for over 20 years, so hopefully you'll consider me tech-savvy enough to not discard my opinion out of hand.
When I got Chrome, my reaction was: This could be the trigger that prompts me to get a Linux-based netbook. I could do all my work in Chrome, and never touch the OS. I'm using Google Docs, Gmail, etc. more and more, and non-cloud based software less and less.
The hyperbole may be overstated in the short term, but over the next few years, this stuff could be the MS killer in my opinion.
