I got my first Mac laptop a bit over 3 years ago. Since then I replaced all our machines with Macs. I'm very happy with that decision and it is highly unlikely that I would switch back to Windows.
I wouldn't buy another windows machine again; I had to re-install vista on my mum's pc and it took the best part of 4 hours to update it, install service packs, install programs again... actually stressed me out! I don't think I'll be switching back to windows any time soon, although I still use it in the computer labs at uni due to software![]()
