I could never agree more.
To me, the "emulation vs. original" debate will pretty much side with emulation as the original systems and games die out. Another thing is compilations- if I/you own five different collections containing Sonic 1, shouldn't that merit the right to play that in Kega? After all, I'm/you're the one shelling out $20 to $35 per collection disc even though they're mostly unaltered from the last one. Also, consider this- how many of the games in a "complete collection" will you really play, especially for systems like NES and A2600 which are rife with shovelware? Emulation just lets you pick what you really want to play (as long as you own/owned the game) instead of pouring thousands of dollars into an 800-1200 NES/Fami game collection and then realizing there's only 200-300 games you'd actually play. And on the "PC emu's aren't good without USB controllers" subject, just put HBC on your Wii and play games on there with a Classic Controller. Problem solved.
