The iPAD craze
This is a step in the wrong direction. The iPB lacks important features from the previous top of the range model RP1000, cost more and requires an iPAD or USB-attached computer to edit patches. There's a lot of MFX floorboards on the market which interface with computers over USB. Why not simply add a short-range bluetooth radio to the MFX and run MIDI over BT to enable communications with any mobile device. It's nice to have an improved UI on a bigger screen, but I'm more likely to carry a smartphone than a tablet on the road.
