Steve Streza, writing on Medium:

You now have a tablet powerful enough to run an IDE, with a very nice keyboard cover, and a screen big enough to encompass all the functionality of Xcode, capable of testing almost every feature of every iOS device ever made. You can code with your keyboard and test with multitouch. You could work on a desk and take your whole development environment with you on the couch, bed, or plane.

This is the next logical step for Apple to take with iOS and when it happens, it’s going to be a huge deal.
