Strangely, this is one of the things I don't really like about OS X. There's nothing to do to it. It just works and doesn't require any real tweaking or customization to be sleek and effective.

It's a point of pride to me that my Win7 box at work is so slick and well-tuned, compared to other peoples' Windows machines. But for the life of me I can't make my MacBook look any better than my Mom's. Nothing makes me happier than being able to be brutally effective on my cool-looking Ubuntu box at home that uses customized window managers and a dozen productivity hacks. But you don't even have to be nerdy to use a Mac well. Where's the fun in that?
