If it's cheap enough, has decent power, and access to certain games that my Switch doesn't have, I may buy one. I don't mind competition.
The problem I have with this is the same reason I can't bring myself to get a laptop. It'll be 4 times the price of a desktop with similar power. I guess If I had tons of money I'd get one, but I don't. xD
But considering you own 5 bloomin' Xbox One's for some reason I guess money isn't a problem for you.
