It's a very good idea, but putting this desk together requires measuring where to screw in the rotating part on both sides, which leaves no room to have a mistake or your desk will look awkward when in any position but the 90' degree angle. Instructions were.... very IKEA. In fact, a friend mistook this FOR something I'd ordered there.  

Upon setting it together, the secondary part ( top table ) revealed itself to be less than stable, and I spend a lot of time worrying over whatever tech I have on it at the time (I have a cintiq I was trusting it with for a few days, until I just couldn't handle the idea of it getting shaken off.)

Over all, this is great for a KID who won't move the second table around too much, and I'd definitely recommend some reinforcing additions later on that might end up blocking the full compact promise of the desk.
