As a Futaba user I posted earlier in this thread in favor of Jeti over Futaba, stating that if I didn't already have an investment in an 18mz (plus a fleet of Futaba receivers) and was starting from scratch I'd go Jeti.
In light of the above posts about touch screens though, its only fair to mention that the touch screen on the 18mz is very handy. I love it and don't find selecting the proper function to be a problem at all.
I find very little similarity between the use of an iPad mini (which I also own) and the programming of a transmitter, and based upon my personal experience I'd say any comparison between the two, unfavorable or otherwise, is quite a stretch.
