i'm not sure if anyone else can answer this... but... heres the thing. I bought the ipad pro 9.7. I bought the 128gb, but returned it a week later for the 256gb.
When i was using the 128gb ipad pro 9.7, the screen's glass felt really sticky. It was REALLY rough, and can barely swipe anything without the feeling of your finger being sticky. I thought it was a 'NEW ipad' thing that goes away after a bit of use. However, it would not go away. After a few days of heavy use, and looking absolutely ugly with finger prints and dust, i cleaned it with a micro fibre cloth (no liquid) and was still really sticky. In the end, no matter how much i cleaned it, it just wouldn't get clean. It felt like a really rough surface.
I returned it for a 256gb, and already have a screen protector ready to put on. I have one for my iphone, and feels absolutely amazing. Easy to clean, and feels like really nice smooth glass. Anyways, i opened up the new 256gb ipad, and omg the screen feels absolutely different. It felt like my iphone 6 plus screen. Or normal glass screens on devices. I thought the new non-reflective screen tech was what made it feel ******, but wasn't. The screen looks exactly the same, after some test in regards to reflectivity, quality, and usage. I could find nothing different. However, the screen is easy to clean, i can wipe dust and finger prints off easily, and my fingerprints dont smudge on the screen as easily too.
Does anyone know why? My bro's ipad pro 12" has the same sticky ****** screen, where he ended up getting a screen protector to make it no so sticky too. I also tried an ipad air 2 before and had the same ****** screen, but returned it due to the speakers giving me a headache.
PS. Despite what people say, i love the ipad pro 9.7. I mean, i'm still a little pissed off about a few things, like no USB 3 for the lightning port, and costing more than usual. However, i'm upgrading from an ipad 3rd gen (the first retina ipad) and its a HUGE upgrade for me. I already had money saved up for w/e 9.7 ipad that was being released this year.
