NO.
Having two separate OS environments kills it. This is not convenience, it's annoyance. You cannot use or take away anything that you had open on you dock, if you take away the screen...
Surface Pro and the likes have gotten things right, since they are fully fledged tablet PCs. You do not have to change the environment once you leave the dock: your pages, docs, movies and w/e keep on rolling seamlessly.
Now had they foregone the dock hardware and integrated it into the actual tablet, would make this - you guessed it, a full blown usable PC. What's ~600 more grams to that behemoth anyway?
For all your Android needs, you can get a cheap, real tablet.
