That's a good idea.
I love me a CRT, personally. As I said in a previous post, I want a PVM.
It's just that the XRGB fulfills another need: putting your retro consoles back in the living room, on your home theater stereo, on a giant huge screen with perfect geometry.
I think its cool to have a CRT den hidden in the basement.... but maybe someday you want to play SNES Super Mario Kart in the living room during the cooldown of a party?
And you might actually play more retro games when they are not banished to a retro corner of your house.
There's also something really appealing about having every console hooked to one TV, and they all look great, from NES to PS4.
