MattCube,
I think it would be cool if you switched up your room a bit...that way you could have the space to add a desk. It looks to me that the way you have everything positioned doesn't take full advantage of the space you have to work with.
Additionally,
I'd recommend selling your monitor and old TV for something like a 32in HDTV....that way you'd free up a ton of space and possibly be able to get a cozy chair or something in there instead of gaming on your bed.
Just my 2 cents
I would have to agree with that i mean that little table thing you work on is ridiculous you have alot bigger table with your space you just dont use it right.
