I'll be honest, other than PC which is hit and miss on which games work correctly even within DOSBOX, I never cared about backwards compatibility. I have almost every generation of systems and until PSX/PS2 era, I really didn't have much issue with the older systems not working correctly. I had to replace the reader on my NES but thats cuz I broke it by accident whilst cleaning it.
I would rather a system focus on delivering quality game experiences than giving me the ability to play last generations games. Thats why I still own a PS3, wii and 360, and will continue to own one of each. Of course thats just me, the rest of you can hate on me for it. H8ers gotta hate ya know.
