Dual booting is a good way to wipe your main system.
All I can say, the Linux way... "Works for me"
Yes, I've had dual booting machines too, in the past. There's always that little uncertainty, though. Especially since Microsoft have a tendency to want to be alone and in control.
Anyway, if dual-booting had worked for me, the way I want my computers to work, I'd probably run it a bit more. As it is, I tend to value continued access a bit too much. If I must reboot I can't be arsed. It's too much of a workflow reset, as I always found myself wanting something from the other OS. Emulation and structured access to data is a much better option, if I can't find a way to do things in the main OS.
