I was humming along with Windows 7 for most of this past week. And then something happened. My browser crawled to a stop yesterday. Im not sure what changed if anything but it was like someone had secretly snuck into my netbook and swapped the 2GB stick with a 256MB module. The CPU kept hitting 100 percent, so browser tabs were taking 15 seconds or more to render content. Thats a productivity killer for what I do, and after a few hours of torture yesterday, I went back to Windows XP.
