I appear to be the only person in the known universe who did not have a problem with Vista. My Sony Vista laptop was fast, woke up out of sleep mode just fine, and if I had any complaint it was with the crap Sony loaded on it, not the OS itself. Vista itself was lovely, though I turned off the damn security alerts.
I use a Mac because The Atlantic uses Macs. And it's fine. Not life changing, not miraculously more awesome than a PC, but fine. And convenient, because all my friends have them too, so we can do things like share power cords in coffee shops. I remain the world's lone apparent OS agnostic.
