Well I know most folks use Internet Explorer, but I've spent a little bit of time using some alternative (non-traditional browsers). Here's a quick review, in order of preference:
* "Safari":http://apple.com. This is the built-in browser on the Mac. Has paned views like Opera. Isn't particularly fast, but that could be because I only have an 800 MHz iMac and everything feels a little less snappy. The panes are nice though.
* "Firefox":http://mozilla.com. This is the new browser from the folks that brought us the original browser. Anyway, this is a super streamlined application with relatively few features. I'm just getting to know this one.
