All of the things I really want, are sort of expensive, so I would feel strange if an actual person got them for me. However, if there was really a Santa Claus, this would be my list for him:

Kindle DX
Any 3D TV
Playstation 3 (no I don't own one yet, and not sure when I'd even play it... but I want to play Fallout 3)
iPhone 4
A little handheld video projector

Basically all splurgy gifts, that if I could snap my fingers and have, I would... but right now can't justify buying.
