Ha! That's pretty much me too - stuff like that's gotta be pretty bad for me to even notice it and even then only when I'm REALLY looking. I actually saw some CA off toward the edges of one of my test shots with the 9-18 when I first got it, but I was pixel peeping after comments from some other folks and that's what it took to see it. It certainly didn't hurt the photograph for the way actual human beings look at photography.
Haven't noticed any flaws with the 20mm Pany at all. Great lens. I wouldn't say its glued to my camera - I definitely find uses for the other lenses, but its become my favorite and primary default lens.
One of the things I love about the 20mm f1.7, is that it's optically excellent (unlike the other m4/3rds lenses which rely sometimes heavily on software correction)... it seems to be made for the Olympus PEN.
