I guess its like 2 factor authentication - I can let a friend use my computer & not worry about them SSHing in to my server. Or I could just create a 2nd account on the computer instead of using Kryptonite (easier in my opinion). I also have to wonder what kinds of backdoor access the NSA has to my phone.
