Have you seen the commercials for this? Anyone know anything about it? I've gotten so used to Vista, it doesn't bother me much, but something about my printer isn't compatible with it (though it advertised that it would be) and is the cause of computer meltdowns every so often. I just wonder if it's worth making the switch. I do have enough room on my computer (at least I think I do). If I switch over, do I lose all the stuff, like wiping out the hard drive?
