Thinking about it now, as much as i would like for this ipad to release, also making arguments as to why it would be great its now starting to make less sense. According to some tech podcast and seeing in the wild (not a big pool i know) but it seems people buy and like keyboard cases for their iPads. It makes sense, for many outside possibly their phone this takes as the main or only computing device, add the fact that the iPad is super simple and fun to use. Also in some cases it is more portable and better to carry around then a laptop. It's hard at this point to not see this in many ways as a reactionatory device due to rising sales of Surface pros. Of course no where near the amount of ipads and or possibly macbooks but it is selling. Also their hasn't been any kind of mention, leak, hearsay, nothing on apple moving towards a touch friendly version of OSX (can still happen i.e. swift announcement) even with WWDC being a little over a month away. And another thing to consider is the Retina Macbook and force touch for trackpads, why work so hard on that technology to then in a couple of months release another product who's main interaction method wouldn't be it.
Microsoft is kind of lucky in that the surface is it's main and only product for windows (not including other manufacturers hardware). It's also arguably the go to device for now for the one of the best windows experience so that is helping it sell more as it's the most in your face choice. And now with the surface being out for a couple of years now it has some mindshare whether it's good or bad. Also then continuing with their philosophy of having the same experience to an extent for all windows devices is slowly bearing some fruit. But they had to ride a tough wave to get the surface to where it is now.
If it is released and can run OSX and iOS apps and is atlease as strong as my 2012 macbook pro 13 then i will deal with the sure lack of ports in exchange for the ease of carrying a tablet versus a laptop. I don't think their are enough people with that share my rationalization for purchasing one to confidently justify the R&D and marketing money that has gone and will go into this iPad pro. It will sell just off the strength of the apple name and new apple thing, but with already declining sales on iPads and tablets in general it's already starting to look bleek for this iPad Pro. But then again who knows.
