I work online, so I can excuse the expenses. I have like 8 different adobe programs running right now with a dozen files in each consuming over 6 gigs in RAM on just that alone. I like things going smoothly so it's good to have excess.
And then when I'm bored I can play BF3 and TF2 and Skyrim.
I can work from anywhere, and I like going to Cafes and stuff to get out of the house.
When I visit relatives, I can take work and play with me.
It's totally worth the $2,000 pricetag.
