I've got 2 teenaged boys (16 and 15) and I can tell you what mine generally want. They ask for video games and DVDs. They also like to buy clothes for themselves, so they like money or gift certificates to stores like American Eagle. Of course fashions and trends change fast, so we tend to avoid store-specific gift certificates. We either use cash or mall-wide certificates. They don't want CDs because that generation pretty much helps itself to anything they want on-line. They are also both tied to their cellphones - we've bought media cards and cellphone cases for them. We've bought them headphones for their ipods. They hang posters on their walls, but you have to know what movies, bands, sports teams etc. they like of course.

On another note, there's been a lot of Beatles chatter of late and I hesitate to add more (it would be terrible if they were overexposed) but a friend recently showed me a film that is worth watching. Apple posted a video of their first concert in the US (7000 fans at the Washington Collesium in 1964) in its entirety. It's a 45 minute set of their early hits, and it is very strange to see how low budget and unorganized it was. They hit the stage and then spend 2 minutes getting their stuff set up and oriented properly before they play a note. They have absolutely no idea of the phenomenon that they are on the cusp of becoming. Definitely worth watching.
