I wish I had that much typing to do that I could rationalize the expense of such a fancy keyboard :D
Also, unfortunately for the high price point it's too hard to actually try those out somewhere. Maybe works if you have friends, but I'm not going to spend hundreds on sth only to find out it doesn't work for me after half an hour. There's probably an option to send sth back, but even that is going to be a nightmare with small vendors.
