IMHO, it would make more sense to develop the Kemper Editor/Rig Manager on iOS and Android than on PC and MAC for 2 majors reasons:
1) In near future, it will be more Android and iOS devices than PC and MAC.
2) When we're not at home or in the studio and we want to edit and/or manage the profiles... you have more chance to have your smartphone or your tablet than your desktop computer. For instance, I love the idea to update the iStomp with my phone without even using any cable at all...
The only concern would be the future of Windows with Win8... but that's another story.
