It's cheating, somewhat, to replace your desk with once that is as wide as two desks. I'm trying to figure out a way to do something similar with only one desk's worth of space.
Long story short, what kind of desk are you working with? I would consider my desk fairly small but it has lots of room for common things.
If I had the space I'd love to have a writing area as wide as OP's, which looks wider than either of our entire desks.
