I just started using
http://www.maxthon.com (formerly called MYIE2) - I absolutely love it after the initial learning curve and kicking form NEtscape mail to Outlook.
What made me finally want to go with an IE Based product? The difference in how quiclkly the actual browser itself boots amount, amount of resources it uses, and the speed of web pages you are surfing.
Maxthon is also skinnable, I went through about 50 different skins before I found the one I liked ;) It has tabs integrated into the browser in the BEST way possible, favorites can be put across the top like "Bookmarks" in netscape except you can have different bokmark sessions spread across that part of your browser.. For example mine are
Links, Football, Domains, Poker, and Adult right now ..
If I click any one of those it is a seperate bookmark list and I can even create sub folders in that folder etc.. It is pretty sweet if you ask me!!
