I'm Danish and have often wondered about this too - there are so many options here for electric height adjustable desks and everyone has them, from banks to car dealerships. I would never work somewhere that didn't offer this, I even got one for my home office: http://imgur.com/A1eS2. Set me back about a thousand dollars, about what I spent on a cell phone every other few months.

Mine is from http://www.conset.dk (Danish) by the way. Huge selection of frames (one, two or more columns) and you specify your tabletop yourself (size, position and dimensions of the cut-in, bezel, finishing (oak/maple/cherry)), all online.
