Don't just think of getting an ipad for Amplifi only. Think of it as opening the door for a whole host of musical goodness. I've got a 32gb ipad that is positively brimming with music apps. Trainers, lessons, backing, amp-modellers, loopers, fx, tabs, chord trainers etc. Many of the apps will integrate seamlessly with each other via Audio Bus. The ipad is one of the few items I have that I would replace in a heart-beat if it were ever lost/stolen/damaged. And the fact that it now controls my Amplifier is a nice bonus.
