Got my iPod Touch 4th Gen two days ago, very impressed with it. It's also my first experience with the App Store, as my previous iPod Classic couldn't utilise them. In those two days I've chalked up around £15 on apps. I'm pretty careful with cash and I'd never go silly on spending, but the quantity, variety, and availability (being able to buy anywhere if you're on a wi-fi network) is quite scary. Nevertheless, enjoying very much. The bulk of that £15-ish sum consists of Guitar ToolKit, Puzzle Agent, and Broken Sword Director's Cut, and I also bought a trio of 59p apps (DoodleJump, Super Mega Worm, and Angry Birds).
