Do not understand the top reviews

I'm really absolute Apple fan and I just about anything from several iMacs on MacBooks, iPads and iPhones to the Time Capsule, but how it can be that the otherwise so critical Amazon customers rate here is almost entirely positive is beyond me. Especially when you consider what is a nonsense for Apple always criticized (iPhones you can bend with all his might - surprise, surprise).

I was totally keen on this machine and got me ordered directly from Apple with 128GB and 4G. The first impression was great: the display almost directly on the glass surface (is laminated) and significantly better performance than the iPad 4 (Air 1 I've omitted).
But after a few minutes I noticed that already occur under light pressure on the display is extreme "shadow". The check against the old iPad revealed: there can be the same with a lot of strength not reach. I thought the iPad would have a defect, so YouTube strives to determine that this is probably normal. For me really unacceptable that the display less "impressions" lässte, even if one wants to hold the iPad in only one hand.
Then I wanted to watch videos and I noticed the vibrations and completely overdriven bass on. Again, the check against the 4 -> better sound, vibration 0.
So for me not acceptable at a price of 800.
