So I worked at Netscape for a while (in the open source Mozilla days of late, not the Pants-era if my unreasonably in-depth cyberstalking is correct) and I think I can pretty objectively tell you that Internet Explorer on the Mac is the way to go at the moment...

Mozilla in full is nightmarishly slow and bloated on all platforms. Win32 happens to have a compiler that spits out ridiculously fast binaries, but Mac doesn't, or at least not to that extent. Writing 90% of a large application in XML and hacked-up JavaScript, with only 10% or so of the core stuff in C++ does not smell like a performance win. Chimera attempts to throw out all the crap and write a native app around the rendering engine. A good idea, but OH GOD DROWNING IN THE MOZILLA CODEBASE ANYWAY you might say...

From Dave Hyatt's weblog (Dave recently ditched Netscape to work at Apple): "If you use Chimera on the Mac, you'll see that the textfield widget is easily the most painful part of the entire application. It's buggy, slow, misbehaves, and doesn't edit the way you'd expect." That's just bad, IMHO.

This is full of poo: "You see the Mozilla browser may well be a quantum shift in how cross-platform client software is developed." How's this for a quantum shift: Microsoft .NET 0wnz Mozilla's W3C-oriented fuckistry for a number of reasons. Yes, using JS and XML as the platform-independent API for writing web apps is a nice idea, but first of all, those languages aren't compiled (hence, your apps will get slower and slower), and second of all, W3C effectively controls almost everything that happens in the XML domain, and they have a knack lately of mismanaging the development of all their standards. They've been turning out nothing but crap since mid-1999. I know this -- I was a member. (Currently working on "W3C Considered Harmful" for some sort of publication or something... Making Geek-Elders Angry since 1998 [tm])

Point being, hedge your bets. Be proud of your switch to Apple, and be not ashamed of your browser choice.
