I would say backwards compatibility is only really worth it if it makes the old generation games look better than they did. For example, when I play PS2 games on my PS3, the upscaling and lossless HDMI output cleans up those games so well that even a PS2 via component cable doesn't compare. The added bonus of less shelf space is a plus as well. That to me is when backwards compatibility is truly a great feature. Even the PS2 cleaned up PS1 games rather nicely because of the emulated graphics chip allowing for additiona filtering. Sadly Sony(and Nintendo with Wii backwards compatibility with the Wii U) did not really promote the graphical benefits of plays older games on those consoles, so many people did not care.
