Those reviews have so much do to with review... Those are more preview of "how cool apple is for providing us those devices"
Because if you would review it you would compare it to surface pro, especially new one and other bigger tablets.
And how amazing is that they call writing "work" try to REALLY WORK on any mobile device like android or iOS. You gonna fail really fast. I tried it many times.
Those devices are made for media consumption and simple tasks like writing. Try to plug your pendrive/hdd modify files. Make some data compilation and create presentation. This is work. I could write review on my old se k800i and put it on web with images...
This iPad pro is his overpriced ipad, that is cool for casual use but for work is useless.
And graphic work? For simple painting and drawing is cool but try to work on huge file with more than 30 layers. It's annoying and slow.
Systems is limiting those devices. All power of modern devices is going to just to run fancy system...
