I would love a desktop with a multi-core processor, and two or more monitors I easily network together.
When I'm using it I want to feel like I'm in the zone. I'd be working hard, reading an article, and gaming at the same time. I might even get into online shopping.
One day you guys might see me logged in here for weeks at a time wondering: "Why is he still logged in? I hope he's not dead." If that happens, then I probably haven't left the house in a while due to being hooked on that desktop.
