Actual destruction isn't relevant. The idea of destroying musical instruments because a new iPad is in town, is jarring. The ad lingers on pointless destruction. Why not spend the time showing the new iPad? It's sad when advertising is stuck so far up its own clever-hole, it loses grip on reality.
Edit: I just watched it again. It's definitely not obvious CGI, not sure how you can say that. Camera lenses shattering, paint spilling, wood splintering realistically.
The press itself is ridiculous, you can't have two skinny cylinders like that pressing out a platen that wide and expect to get any reasonable forces. Maybe it's too much time watching the limitations of the 150 ton press, but it all just seemed like someone's idea of what a press is, instead of an actual press... in hyper-real cgi.
