I don't use my desk, either. I have one, but it is more of a table. It collects useless things on top of it. It's in the spare bedroom, but I'm never in there. I could go weeks without venturing past that threshold. I wonder if the monitor even turns on anymore! I just move my laptop around the house, from room to room. Or use my tablet.
My desktop computer (custom built) is actually my TV, and that sits on a nice entertainment center in my theater room. It's in a custom case made to look like a piece of A/V equipment. That's all connected to a projector, 124" diagonal image.
