Its not really a single platform
Except it is.

Its only USP is the touchpad on the controller
So being absolutely free to develop games, for anyone, isn't a USP? Is the open nature of the console not a USP? Is the free to try of every title released for it not a USP? (I remember when devs cared enough to release demos, now it's "betas" a week before release

but then its even dubious if thats preferable over a normal touch screen experience (which itself isnt great).
No one is forced to support touch controls on the system. You're right, touch gaming sucks, full stop
If you're expecting COD 12 or FIFA 2017 it isn't the console for you, thankfully. I just hope there are enough open minded individuals out there to stop it sinking. I'm going to use mine for media and emu duties so even if it does, it's a bargain
