Well, I got what I wanted long before christmas (meh mac) so unusually this christmas I might get more than one thing, I normally just get one big thing.
Copy of Vista Basic for my mac: So I can play DX10 games in bootcamp
iPhone: Both my parents have them, and I would LOVE to have one.
Copy of some games: GTR2, COD4, Dirt, ect.
Maybe:
More car stereo stuff: Rear speakers, amp, sub, ect.
New reciever for my room
New speakers for my room
Another lens for my XTi, 17-55 2.8 ef-s or a 70-200L f4 (my father has the 2.8L IS, it's mind blowing)
Some way to get a Leopard capable macintosh notebook, new or used, it doesn't matter.
Maybe some type of HD television
What I find more difficult is what I am going to get other people. It's not that I can't or won't pay for it, it's what I should get them, as the people I get them for are hard to shop for.
