My iMac/Scanner/Printer/Wacom Tablet: I use this for all my art "work" that needs to be edited with a computer. The Mac lets me see the tiny details in my stuff that I can't see on my family's Windows PC. Plus, it's just nice to have a computer of my own.
My "Xbox-Ready" TV, cheap Surround Sound system, and Xbox: What can I say? Gaming rocks with spooky cool surround sound.
My Game/Movie/Anime collection: These are my pride and joy. When I'm bored, I can use any of these to pass hour upon meaningless hour. I'm a bit of a collectionist as well...
Before anyone says anything about me being spoiled, the only thing that I didn't buy myself or helped pay for is the Printer/Scanner and a couple movies.
I mean, this is the only stuff I spend my money on (not counting Amber, naturally)!
