I just bought the iPad Pro 9.7, and now loving it. The speakers are amazing, and I haven't had a chance to get the pencil just yet, but I'll pick one of those up soon. What apps would you guys recommend? I have noticed that YouTube does not support PiP unfortunately. I am mostly using this iPad to replace my MacBook Air. If I need a full computer, I have an iMac at home. I installed MS Word already. So what other apps? Mostly productivity ones...that are optimized for the pro?
