just found out these exist and want one. Seems there are 3 different kinds http://store.steampowered.com/hardware/#Machines Anyone have any experience with one? Which ones the best? The Alienware one looks the coolest imo. Or are these even worth it at all? Seems like a flashy cheap consumer concept to me. Isn't it just a small PC running Steam Big Picture or something? Either way, would love to hear some first-hand experience.
