It's a feature that I'm still perfectly okay with.....While the advantages of digital is quite enticing, I personally still prefer a medium that requires you to physically swap a disks for the added security and freedom (like Calmador said).
Yes you don't have to worry about games getting scratched, lost, broken or swapping (I had to replace my original copy of SSBB), but I'd rather still use a medium that doesn't go corrupt (like the way digital does), I don't have to worry about DRM, hacking, or anything of that sorts.
Though you're op is speaking of disc based specifically, Nintendo seems to have made it a little more convenient with hot swapping games on the 3DS.
Physical based content is a much older form of technology, but it sure's hell not an obsolete one. (Though I'm not saying that your op implying this)
