memory cards, usb drives? I know I go thru a massive amounts of these.
Another gift might be an external hard drive for his computer?
Any accessories for ipods, headphones? Headphones are big for me because I run with them on a daily basis and tend to destroy them fast.
I know I'm a girl, but my mom buys cases of Gatorade for me for Christmas

I get a case of my favorite Gatorade since i'm a runner and don't drink soda.
[my mom finds that i drink an incredible amount of this]
My mom gives me socks. I know, who wants to recieve socks but with cross country and track; I go thru socks like mad.
Another idea is if he is planning to do something like a trip later in the year (like something that needs flights or something); give him a little plane and write a letter that states you will buy the ticket at the time of the trip. I know I'm getting a London, England postcard with money (at the time of my trip) for my class trip in may.
toiletries are always good
