yeah, WebCore is pretty nice, but it has annoyed me how Apple havent really contributed much (if anything at all) back to KHTML though. :-\
Even still, its nice to see that there isnt any Mac users around that use a browser that sucks anymore.
I just recently installed Firefox "Deer Park" v1.1 Alpha 2.
Nice, Fx is actually not hogging my RAM and CPU time for once! ^^
I tryed Opera 8 last week, and I was really glad to see that they have followed Firefox's footsteps a little, and simplified the interface alot. It still feels akwad to me though (you can customize it, but Opera's customization system sucks), and the big ad in the corner annoys the hell out of me. And I havent seen any new eye candy in Opera since the first versions of 7 either.
