Not quite ready to shell out $400 for an iPhone? Your teen will forgive you if you put this under the tree instead. The Touch has the look and feel of the iPhone, but without the calling capacity. The 3.5 inch wide-screen and simple-as-can-be touch interface are here, as is the elegant zoom-- just a finger tap away. Teens will focus on the 1,750 songs, 10,000 photos and 10 hours of video they can store (and that's the cheaper model!), but you should focus on the Wi-Fi ability, which makes web browsing possible. Sure, they can use it to wile away the hours on Facebook. But they can also read countless international newspapers (a great way to practice that French!), browse YouTube to get help with calculus problem sets, or do a daily brain puzzle on the way to school. Plus, with free applications like "Remember the Milk", they can add homework assignments on the fly and set a reminder to go off later, when they're in the middle of their third episode of Heroes.
