Hello guys! I received my ipad mini 4 yesterday, I'm really pleased to say It's a great upgrade from my older mini 2.. I'm very impressed with it. No sound vibration issues as(very good and improved speaker performance indeed, not like my parents's ipad air 2...), wonderful new laminated display, with excelent color gamut, on par with ipad air 2 display(and the sense that you are touching each pixel). The cameras are a big upgrade too, and the processor, althought is not an A9(this the only option that Apple could have use in the ipad mini 4 instead of a8, because a8x or a9x need much more space, battery and it runs much warmer), the important difference is 2gb ram. This a key upgrade, because really improve the user experience. About new cases, the solution of two separate partes is a clever option, because you can pull of the cover when you want, and use the ipad that weight less in that way(and ipad is still protected by back case!). So the combination of less heavy ipad mini 4, and the option to pull off the cover really improve the feeling on your hands(ipad mini 2 weights 30 gr more and leather smart case is much bulkier). Of course, the quality of case and cover is top notch BUT...the price is very very high. Please apple...104€ for a complete silicon case??LOL, if the apple products are expensive(a very well spent money in my opinion), their accesories are LUXURY product. Ok, it's Apple... So very happy for these news. I have only one query for you...My older ipad mini 2 has 9.1 pb1 version, so when I've tried to configure the new mini 4 from with my mini 2's icloud copy, the system tells me that it impossible, becouse mini 4 had to have 9.1 installed. So, I've tried to update mi mini 4 without success. I've done all necessary steps, but iOS 9.1 PB1 isn't showed in sofware updates... Anybody has been able to update new mini 4 to 9.1 PB1 or apple still has to release this version for this new ipad?? If I can't update it, I will have to copy preferences and dowloads apps manually... Thanks you very much!!!
