I still use my Wii system for Wii games. They look horrible on my TV through a HDMI cable anyway. It's a bit old plasma TV, but one of my friend has a modern LED tv, and Wii games on his Wii U also looks like trash compared to the output of the old Wii. Artifacts, no screen smoothing (done by TV but not through HDMI).
I also use my DSi XL for old DS games, almost same story. DS games are way too blurry on 3DS because of the not too big difference in screen resolution. If the next handheld has a higher pixel density like the Vita (yes I love that screen), then I'd love backwards compatibility. PSP and even PS1 games looks really, really good on that screen. Pixelated yes, blurry no. Blurry is even an option there for you poor souls who like the look of DS games on 3DS :P
But if it continues like DS -> 3DS and Wii -> Wii U, then I have no qualms about keeping the old systems. Well, was always going to do that anyway.
Backwards compatibility, not a selling point for me anymore.
Yep.
