If what you want is a device, running a traditional OS, then why not buy a Microsoft Surface? Why do you want Apple to make one, and potentially rape you on the price? Quit bitching, and go buy a Windows 10 machine with a touch screen.
I'm quite happy with my new iPad Pro, used it all weekend, and didn't turn on the 27" iMac retina. I do hope you all keep buying Apple products, as I have a lot of Apple stock!
An Ipad with a desktop OSX would sell tons more than the iPad Pro.
