the magic keyboard has slightly more travel than the MacBook Pro, but not by much. It is actually just magic keyboard 1. The first keyboard was not called magic keyboard
As someone who owns the 12" rMB, 13" Pro without TB, and the Magic Keyboard I have a good idea how they all feel.
12" = lowest travel
13" Pro = right in the middle
magic keyboard = most travel, but still less than the original pro, air, etc.
Just got test them in store before you buy if you are worried. Don't assume b.c you hate the 12" keyboard you will hate the Pro keyboard. They are slightly different, and it could have enough travel to change your mind. I personally like all of them. I think the new Pro is the best of the 3.
