Top 5 Reasons I Made the Jump:
- It Just Works
I've been running my new Mac for over a month now, and the only time it even came close to crashing was when I used Parallels to boot into Windows XP. - Cross-Platform Compatibility
When I picked up my MacBook Pro, I brought it home and plugged it into my home network. It automatically recognized the other PC's on the network and I was able to drag-and-drop files between them. Out of the box. - Time Machine
Finally. A backup utility that you don't have to think about. It just works, and then when you need to retreive something out of the backup, you grab it. Done. - No Drivers
Apple doesn't use drivers. Why struggle? - Microsoft is in big trouble with Vista
It's no secret that Microsoft has painted themselves into a corner with Vista. People are downgrading from Vista to XP. I rest my case.
