I see your point.It's about different people working in a different way and having their own point of view.So for me playing guitar means not to have to mess around with an iPad .That's just me though!
Well, I wouldn't like to have my laptop and a USB drive to transfer, add or remove some profiles because I want to play guitar and not have to mess with the computer at all...
But even if we could have 5000+ profiles already loaded in the KPA with Amp folders and Favorites setlist, and of course without increasing the "already too long" booting time (which is currently not the case), there would always be a moment you would like to add a new profiles (because human beings are never satisfied)...
So, in that case, I just hope I could take my phone (because it's the only devices I ALWAYS have with me, wherever I am), download the profile from the internet and send it to the KPA... perhaps even without any cable, that would be even better...
My 2 cents
