Browser list as it comes to mind:
Internet Explorer: Very likely. It is small and compact, and has an OS X interface. Granted, it is
Microsoft Internet Explorer, but it seems to be a very favored browser.
Chimera: Unlikely. Sure, it has the promising attire and speed, but it's a beta browser. I cannot find one common app/utility with a version number under 1.0. [Everyone starts looking...] My point is that Apple most likely will not use something still "in the works". Probably once Chimera reaches a full, effecient 1.0 Apple may adopt it somehow.
Netscape 7: You're better off playing the lottery. If you know some poker guys, get together and have a blast. Four people or better works best.
Mozilla: Don't forget the potato chips and your latest fishing stories.
Both of the previous browsers take a tremendous time to load, even on the Greg Dan'd fastest Mac you have. Stability is a further issue to disregard either of the browsers to succeed as the main browser for Apple in 2003. PS: Flash support is sort of crappy.
OmniWeb: Looks cool. Pretty stable, also pretty. But it doesn't seem to have a lot of browsing speed compared to other browsers.
There are several few other mini-browsers out there, some payware, but I have not seen Apple support a minor-league browser.
As for AOL: Go to he!!. I converse back and forth with my biology teacher (now retired) through email, but she cannot receive her mail from AOL. She talked on the phone with the d**ks there for 40 minutes, enough time for a whole round of poker games. I refuse to see Apple support AOL. If people need IM, use iChat.
Best bets: IE, Chimera (non-beta)
