Do you write any code? Because that is not allowed on iOS. Do you want to browse see an application and want to use it? Because that is not allowed on iOS. iOS is so far from being a useable OS that I don't think it will ever be anything more then an internet machine with light video and image editing capabilities. The last update to the ipad pro should tell you enough about what apple thinks constitutes a "professional" OS.

That being said OSX running on a higher specced ipad pro CPU could be really awesome but I don't think that is what will happen.
