You'll undoubtedly smile when you happen upon your favorite station from your angst-filled teen years. (Like this? Check out Pandora)

The dust has cleared and yeah, some stores sold out. But the iTunes Application Store trumps all that hoopla. With more than 500 apps, you can pinch, tilt, flick and tap your way to more options than you should ever be allowed to keep in your pocket. Free to $40, at iTunes.
