I'm at school right now and thought I would post a screenshot of the "About this mac" bit on the computer I'm currently using. I'm posting it because this computer, and many ones like it scattered across campus, is the reason I almost didn't get a mac myself. I thought all macs were like this. I thought they would all be slow and have near-non-functioning keyboards and mice. I didn't realize how old and outdated these computers are. I didn't realize that they are probably nearing ten years old (compared to probably 4-5 years old on most of the PCs around campus). So if you're thinking about switching- don't judge what a Mac experience now would be like compared to previous Mac experiences you've had.
