PlayStation Vita, you may want to hit up your local GameStop. Keep in mind that said unit will be securely bolted down, because its a demo unit, of course!
The retailer has announced that it now has demo units at over 3,300 of it's locations, allowing customers to try out several games, including Uncharted: Golden Abyss, Little Deviants, Modnation Racers: Road Trip, WipeOut: 2048 and more.
Just remember: Wash your hands. It's flu season, after all.
