Games do you are right, but productivity work is much like sitting at a desk in a cubicle -- just with so much much more you can do, even now. Sure, today there are a lot of caveats, like you need to touch type and transitioning between controllers and keyboard is sub optimal on the hardware side; while the software is still all 99.9% game oriented, there's no native multitasking, even little things like cut/copy/paste are a hassle. Today, your only option is some version of screen casting with all its multiple window resolution/scaling pain. But once you get it working it is hard not to be amazed working on a 10foot tall visio diagram and by the time Apple rolls anything out all these problems will have been solved for all practical purposes.
