What do you use Mac or Linux?:D I'm trying to avoid this topic at all costs. If they like Windows... good for them. That's the extend of my opinion .
I hate Win, and managed not to have a Win laptop for 2 years now (proudly using my mac). But now, I'm about to start my MFE and think I need one to work with others in my classes. Still, my new laptop has dual-boot (with Ubuntu) so if I find it feasible, I will use it for everything. Win 7 is better than previous Win OS. But still, I had more errors and reboots in 2 weeks with Win 7 than I did with Mac since 2008!!!!
