I have seen them. And no, they didn't do a lot more than retouches. There's no "unwatchable" scene because of "distracting" CGI. It fits nicely into the background, like it should. The reason you get distracted is because you're looking for reasons to hate, not because they are actually distracting.
Excuse me, but what were you watching? The new CGI stuff not only messes with the scene composition, it also fucks up the story. Tatooine used to be a boring desert planet where nothing interesting ever happened, so it was quite understandable that Luke wanted to leave it. Now watch the Special Edition with a Mos Eisley that is suddenly a happening place with loads of activity and Luke's motivation is not that obvíous anymore. The CGI stuff in Episode IV also doesn't blend in with the whole look of the film, it's too clean.
And no, I for one am not looking for reasons to hate the new versions. It's far less noticable, and therefore less distracting in Episode VI where I don't mind the added CGI at all.
Apart from that, Greedo shooting first was plain stupid and the added Jabba scene was unnecessary.
