Apple make the best computers available today, and they have the best OS. The only time I use Windows is for playing Counterstrike and Far Cry. To me, a choice between a Mac, and a Windows PC ain't no choice at all. It's like choosing between a Ferrari and a Skoda. :-)
It's a cliche I know, but on Mac things 'just work'. Wi-fi, Bluetooth, USB devices, digital cameras, everything I plugged in, Mac just recognises it, and it starts working right away, no need to search for a driver CD or install any proprietary software or restart the computer, it's just there.
