At CNET there’s a comparison of Windows 2000 vs Mac OS X which comes out in favour of OS X. I’m a bit dubious about the higher OS X score for hardware compatibility, but it’s pleasing none the less. I currently use 3 machines on a regular basis. One runs Win2K, one runs Linux, and one runs Mac OS X. They all have their pros and cons, but if I could keep just one, I think it would be the Mac. I find myself pining for it when I’m using the others and, for all its current limitations, the reverse is seldom true.
