AOL Releases Client for Mac OS X with Gecko Browser

DietFluffy writes "America Online released an update to their Mac OS X client. The built-in browser is powered by Gecko! However, America Online plans to stick with Internet Explorer for their Windows client. Will this make web designers think twice about tailoring their web pages to Internet Explorer? Or will they ignore this, given that the Windows client will still have Internet Explorer as the default browser?" And if this goes well, will the Windows version eventually use a Gecko-based browser, too?
