I read in various reviews that the IPAD Pro speakers sound better than the Ipad Air but are they comparing modern IPAD Pros? For anyone that has upgraded from an Ipad Pro 10.5" to modern Air, do you take much of a hit in the sound department? Also do you miss the 120hz refresh rate or do get used to the 60hz of the Air? I still love my 10.5 Pro but battery life is now is taking a big hit (but not according to Apple, long story) so sooner or later am going to give in when I see a good Air special. The sound and refresh rates are the only two things I am worried about, otherwise don't see the need for a Pro11. Maybe if they used the same mini LED screen technology as the bigger version but they don't.
