I don't get it. The Google Blog says that it is clear that users want their email faster with less hassle and all that jazz... I would like to know who in 2009 is having so much trouble checking their email and getting online? The main thing that slows you down is network routing and web servers being overloaded. As neato as this OS sounds... the fact is that it will probably have driver issues, will not perform gaming worth a shit and will have nothing but half ass working open sourced apps available. (with the exception of chrome and open office and few other very well maintained apps) It may reboot from desktop to desktop in 25 seconds... but what good is that when you can't even watch a streaming netflix during your lunch break?
In addition to all of that, I tested Windows 7 out around 4 months ago and it was pretty smooth and had no driver issues... I have not tested the Release Candidate but I have heard nothing but extremely positive reviews, including benchmark scored rubbing out XP. At work I use Ubuntu because it works better than windows with the environment i work in (Trusted Desktop). But the fact is for a home user (and everyone else i work with), for gaming, work, compatibility and ease of use... Windows 7 is going to take the market. And the market is Desktops and Laptops. Netbooks are nice... but when it comes to people who actually have work to do and not just dicking around on the Internet all day, they are pretty useless.
