I use an Ikea Gallant desk. My main computer (home built Linux system running Windows via VirtualBox) sits underneath, and a large-screen Asus monitor is on top, as does my laptop. I try to keep the physical desktop devoid of non-essential stuff, but this is a losing battle. I also have a video projector directed at the wall in front of me. My office is full of books, plants, my LEGO projects, and other miscellaneous…
There's something really great about the Gallant desks. Cheap, roomy, well built, no fuss. I have the version with T-Legs, but I can't honestly go back to other kinds of desks.
The table top is starting to get a little crappy with some of the finish bubbling off due to my constant resting of hands so will just need to purchase a new one at some point - but no real rush.
Very sturdy desk overall, it's small - but with monitor arms for 24 and 17 inch displays I have more than enough desk room for keyboard/mouse and notepad.
