What innovation and research. It's the same device since the first iPad. Only thing change is it's speed, and the CPU costs seem to stay the same every year. Still, the cellular versions are WAYYY overpriced. Don't get me started on the extra $100 every time I want to double my capacity for something that costs them $15.
Yeh because processors design themselves and making it lighter and smaller took Jony Ive all of 5 minutes with a couple of sketches on the back of a cigarette packet which he sent to Foxconn and they said ok mate how many you want.
Oh and providing all the services and new software versions for free also costs Apple nothing. And they get to use all the cellular patents for free as well. Get real.
