I might have missed an update in the past couple of days, but, otherwise, the experience on a fully up-to-date iPad Mini is the same like in Android in the past. Maybe a bit worse, too. It happily crashes, lags, as in, the touches take a couple of seconds to register, and overheats the iPadlet like I've been using the pen for 30+ minutes in the summer. Also, I can not understand why they do not have the custom themes on mobile, Android or i*OS.
