For me, it's mac at home, windows at work. I work mostly in Microsoft Office, and it's just not very good on Mac. Also I prefer the start menu because the way I use it, it has labels so I can see at a glance what document I'm trying to get at. And I can't stand not having tree navigation in finder. Opening two windows to copy something to another folder is super annoying. But for home use with photos and music, I'm quite happy to use mac. The laptops are undoubtedly superior in terms of hardware.
