The filesystem is annoying but not a deal breaker for me. The biggest problem is that it's a "unixy" filesystem, but it's (by default) case insensitive. You can format it to be case sensitive, but there are some apps that break; a major example in the past was the Adobe suite. When I was doing web development, I used my Mac because it basically had the good parts of Linux and Windows for what I was doing. Both Ruby and Python work great, and http://pow.cx/ http://pow.cx/ makes Rails development really nice when you're working on multiple projects. On the flip side, I could use Photoshop when I needed to without needing a VM or dual-boot. Linux is a way better ruby environment than Windows is, and Windows is a way better environment when you're dealing with clients (Word docs/PPT, PSDs, etc). OSX is kind of the sweet spot in the middle. Now that I'm doing more DSP and embedded type work, I still use the Macbook occasionally, but most of the work is done on a dual-booting Windows/Linux Lenovo. Linux for writing code (arm-gcc-none-eabi) and Windows for CAD.
