LOL. The iPad 3 comparison. It was the first retina iPad and a lot better buy than what people say. Actually, it had way more of current technology by release than iPad Pro. I bet when iPad pro 2 is released, the flaws of iPad pro will make it the buyers remorse pad.
It is heavy, charges slow with full charge error, does not have current Touch ID technology, can't charge while in use with much brightness/load, has no pro apps yet, has no relevant apps updated to support the larger screen, has super bad accessories and is very underpowered for a pro device.
Multitasking is hideous also.
You really need to quit saying that the iPP can't charge while being used. Mine does, and I have the screen not full at full brightness, as this is too bright unless you were maybe outdoors in bright sun. At a comfortable screen brightness, comparable to a desktop monitor, the iPP DOES charge while being used. When you just make **** up, you sound like an ass.
