Re: MS can dump Surface at cheaper prices, but if they do, they lose their partners.
Toy tablets: ALL units without an inductive digitizer and ALL units that can not be used to develop software for themself on it. So the iOS, Android and quite a few x86 units qualify. Those are nice for media consumption but nothing more. The equivalent to a toy poodle. Cute but a hunter will always prefer a standard or grande (Both are excellent retrievers)
As for the rest of your "claims":
+ Windows runs fine on Atom based units that are quite similar in weight, size and endurance to ARM based systems
+ If your AV program sucks resources - you are using a bad one. If you use a 3rd party one under Win8 - you waste money
+ Modern works and from the looks it's no better/worse than what Samsung delivers
+ You obviously never used an inductive stylus. It allows things you can not do on a capacitive digitizer.
* Note taking one handed, standing like a legal pad (and in case of Windows later running HWR on it - Android is either HWR from start or none)
* NOT having to do the "smear to enlarge, smear to select, smear to shrink" moves when reading most forums
* Drawing like a proper drawing board with pressure sensitive pens
