So first one is no voice call OK leave that some people belive that its not necessary for a tablet to make a call I agree but sometimes you will feel the need for that
Another is weight about 662g its a lot of weight to hold a tablet for several hours.
No support for USB yaa its cost more than 4k but its not providing the features of 10k devices it really irritating because you will need thing today or another day. I dont know why apple is doing this to his coustmers. It may be because of safety problems. But I dont know the exactly region behind this
Is a dual core dont get me wrong because its dual core works faster than quad core of many devices apart from that everything is fine
Like it has 4g connection 8 mp camera ios9, 1.7Ghz, 2gb ram
So go for it if you are unsatisfied with my points
Its a better tablet but not best.
