pretty cool. I've been searching high and low for a desk that works for both my and my fiance, but it's tough. I've considered building one, but I just don't think I have the time right now but yours came out great.
One thing you might keep an eye out for is an old style "student desk"
They're bigger desks, typically 3x5 feet with drawers on 2 sides, made to be used by 2 people at the same time.
Another possibility is take 2 file cabinets from a used office supply place (or garage sales), face one set of drawers to one side, the other to the opposite side and throw a simple desktop/glass slab/flat door/ sheet of 3/4 mdf on top.
I did that at one point and it wasn't the prettiest thing, but it worked fine.
