You have the freaking dragon, forget these XD Jk. I still prefer my Windows XP though. Media Center Edition, and it has this huge awesome widescreen monitor. Wouldn't trade it for any smaller laptop in the world.
And I think Microsoft recently joined since there was this thing on HP about it. Apparently Dell started it first. But I had no idea Apple joined in. RED Macs? O.O
