Yes. I'm completely willing to own both copies, but the memories are indelible, despite perhaps only having seen the original Star Wars a few times (we lived out in the country without a VCR). So I noticed the changes quickly.
Even the Gweedo scene, without having ever gotten on a Star Wars website, I noticed to be not quite right. There was just too much shooting and I thought I was crazy. And the Mos Eisley scenes, well, what can I say?
