Seems like v1.1 fixed some important stuff, but I don't remember what the problems were at the time. I'm sure others will comment on the fixes, I think quite a few here use the wifi and apps. I do agree that it will help attract the younger folks and I sure hope you are successful in that area at your shows!
I got the wifi when it was first released. The 1.1 upgrade came very soon after, which I upgraded to. But, after trying my wifi unit briefly, I still preferred the remote and went back to that. Should probably try the wifi again now that they have improved the apps and added the deluxe app (which I have updated to, but never tried) with most of the features of the remote.
Good luck and I hope that helps your wifi operations.
