Handheld gaming general

The Xbone slim was sold for around 250 bucks during the holidays. It was the same price as a UHD bluray player AND could play vidya along side the UHD disks. That's a sweet deal for a normalfag with a 4ktv (which are relatively cheap now). PS4pro can't even play UHD bluray disks, what the fuck were sony thinking? They could have made an even bigger killing.
