Apple's App Store is a dangerous place, much like Amazon's one-click ordering. It's far too easy to throw caution (and money) into the wind when new and exciting games are just a simple button press away. With iPad's more expensive games going front and center on the iPad version of the App Store, who wouldn't want a guiding hand to give you a better idea of what to expect for your money?
Luckily, those guiding hands are here. Unfortunately for you, they're mine. I don't have afros on my hands, but if you're looking for a tour of Plants vs. Zombies HD, Mirror's Edge and Geometry Wars: Touch (yes, it does work on the iPad), this video is for you. Warning: may induce nerd drooling.
