I'm really surprised not to see any thread on IOS13/iPad OS. There are so many things that will make my 201812.9 Pro experience so much better that I just kept hurrahing as it was spelled out (but so fast hard to keep up with). And then as people got hands on and tried different things my smile got broader and broader. Ability to use external drives has been on my list for a long time-I have photo files going back to 1998 on drives and it's the primary reason I use my MacBook Pro now. Files app being improved was high on list too--and two windows side by side of same app. I live in split screen, often with slide over. I have had iPads since week one of iPad one-when I was a long time Windows user with a custom built PC. I gradually moved to Apple and several years ago went all Apple-primarily because of the system and continuity. This is sort of like the culmination of the possibilities I thought I saw way back when-and there is lots to go system wise and iPad wise. So-bound to be others happy with this year's WWDC, especially for the iPad Pros.
