I wiped my HDD, which was dual-booted Ubuntu 8.10 and Mac OS X 10.5.6, so I could dual-boot Mac OS X 10.5.6 and Windows 7.
Windows 7 has been pretty good for me up to now, but in all honesty, the only reason I installed it was to play my XP-based games(i.e Halo CE), and they're pretty laggy, tbh...
Overall I like it, but I haven't used it for more than a day in total. It doesn't have Pixelmator, which as of now I'm relying on to do all my graphic design work on(I'm not a graphic designer as such but often get asked by friends to do forum signatures and stuff for them, and I just love messing around, so I spend a couple of hours a day on it), which is Mac OS X(10.4+, I believe) only. Also, my external HDD with ALL my media on is HFS+ formatted, and I'm trying not to pirate stuff(only driver that works is Mac Drive which costs money) xD.
But it seems pretty stable, tbh. I've not had any problems.
