The Wii U, particularly the black one, is great to look at but easily attracts fingerprints. If you've been thinking about maybe putting a protective skin on the Gamepad, maybe consider one like the "Retro Horizontal" skin from DecalGirl. Or choose from a dizzying array of different designs, available in either a glossy or matte finish.
Looks pretty amazing, I must say. There are game themed skins as well, including Assassin's Creed and Ghost Recon, although sadly I wasn't able to find a Monster Hunter themed one. Are you listening, DecalGirl? :)
