I agreed with full OSX tablet. That would be really nice. As of now, Surface Pro 3 is the best tablet/ultra notebook you can get. I cam from iPad Air and multiple Galaxy Note including Note Pro 12. They are nice, but I think Surface Pro(first gen) outperform all those. Now, SP3 is really really nice. If Apple decides to release iPad Pro 12/13 with full OSX, I will swing back to Apple.
I know sometimes (hmm a lot of times) QA teams find problems but the management says they are livable and it's okay to ship...
