There is a real downside to working with a walking desk that the industry hasn't fully acknowledged.
When you aren't sitting down, the cat cannot jump up onto your lap and lie there enjoying her human heat-source. So instead, said cat will jump up on the desk and try to annoy you into picking her up by covering the monitor or batting at the cursor on the screen.
This makes the merge window "interesting". At least I haven't bought into the touch-screen crazy - another "improvment" to technology that people clearly didn't think all the way through wrt cat ownership.
