After ten years on Windows systems, I woke up one morning and said "I think I'm gonna buy a Mac". It was  one of the best things I could've done.

Initially I was not interested to migrate to Vista - there were many problems at that I didn't want to deal with at the time - and perhaps a little quality time with it would remove all fear. When helping a neighbor troubleshoot an issue on her Vista machine, I found the interface to be madly unintuitive and like XP, very slow to start up from a cold boot.

Though the mac is a "niche market", it runs all the cool Windows apps, the open source community is incredible and my favorite feature (drumroll) it runs UNIX under the GUI, an enterprise class OS that has been under development for nearly 40 years.
