Okay sorry for the double post, but I'm slow at editing. This desk is probably too big for the room, but I got it on CL for $20 so wassup. It retails in lower four figures so wtf. I bought it from some people who had their house foreclosed on, so who knows. Beware of my redneck tendencies showing.
Okay so this is how I normally work sitting down. My laptop is up on this black thing that goes across sitting on my desk so that it's lifted a little so I can use my wireless keyboard and mouse comfortably. It also lifts the screen up to eye level so it doesn't just destroy my neck. The thing the laptop is sitting on isn't attached to the desk, but it can only slide forward because it's the exact length of the inside of the hutch.
I keep this little thing in storage up above in the cabinet. It's made of the same shit as the piece my laptop is sitting on in the first picture, except it's shorter and has little feet.
This is a better picture of the thing and the little feet. You can also see the shitty spray paint job I did on it.
So the little thing stands on the bigger thing, and I slide the bigger thing out towards the front of the desk a bit. It's still stuck between the sides of the hutch, so it can't slide off sideways. I use the keyboard that's actually a part of my laptop when I'm standing, and I have my mouse to the side like this.
