Why not dual boot Windows and Linux? Or Windows and a UNIX Variant (ie. BSD) again there are many discussions about "What Distro's the best." "What Operating System roc0rs your s0xors" and so on. Go with what you like and what you feel is better for you. as for OpenBSD, it has different features and functions than Linux, and doesn't use Bash mainly as it's main shell, there are loads of other difference too, but it's 12:30, I'm lazy, I'm chatting on IRC trying to get Syini666's site working right, and I have school tommorow, so I won't go into it all now. But dual booting would be good, so when you need one Operating System it's there and when you need another it's there.

Good luck.
