If you find Windows XP slow and boring, and Vista interesting, but maddening, Microsoft offers a nonverbal apology.
Windows 7 is set for release this fall, in time for Christmas. Not only that, but you can download a free evaluation copy of the release client (the version MS hopes to release in it’s current form; it’s more than a beta, less than the real thing) from Microsoft through July 1. It will run until March, when it will shut down automatically every two hours, then end completely June 1, 2010.
I’m running the RC on my home computer and it’s awesome. It’s a massive improvement on XP, without the bloat and frustration of Vista.
If you’ve got some confidence in your tech abilities and a spare hard drive (or partition) download it and have a go.
