I always hated Windows for not having it, but it's more of a programmer tool, hence why Linux only seems to have it. Once you get dual monitors though, it becomes more of a hindrance usually, especially with Windows buggyness.
I've always wanted dual screens. It feels like it would increase my productivity sooo much.
This. I would seriously LOVE to have a better PC setup. A crappy Sony all-in-one won't take me over. But luckily I'm going to boarding school for high school starting this fall so my parents are getting my a MacBook Pro. I'll probably dualboot Mac OS X besides Windows 7.
On the side note, can you still get Mac OS X updates on a dualboot Macbook Pro?
