They sure didn't ! Ok a couple of hours in and it's flakey! Terrible trouble connecting it to the internet, bsod's left right & centre when installing sound card & services failing to start all over. I've taken it off my main machine with the intention of having another play with it once I've put the baby to bed (literally).
I'll stick with the former comments though, the interface is very very nice & I've had time to play with media centre & that is much much improved over the Vista set up. I think I might persevere with this just for the fun of it.
