I brought an Xbox one once. More or less for the same reason you did though not so extreme.
I had it for 2 days before returning it for a full refund.
Its awful.
I always felt "backwards compatibility" was a strong term anyway .. unless somethings changed since I last looked it up its more like a "free download" if you previously own the game. And when it took me nearly 12 hours to download Killer Instinct, I didn't want to go through that bs again so I just got rid of it! I know I don't have the best internet connection. I thought I could bypass the whole download shite, or at least most of it because I brought a physical copy of the game but apparently I had to download the whole thing anyway- and it wasn't even very good ...
So yeah. "Sucks" is a good way to put it.

My last console was a PS2 (PC DVD's were still in limbo), ran GTA:SA and a shit ton of other games through it, then got back into PC games again.
That's rough, both Disney and Xbox faces not happy. Guess I'm looking forward to the unwrapping and final conclusions.

Disney face was a smile, actually, haha. That's my smile when I'm feeling cheeky :P
I'm clipping the footage now. Seriously considering returning this ball of ass.
