check out this Slashdot story about Phoenix 0.2: http://developers.slashdot.org/developers/02/10/07/1739241.shtml
I remember Mozilla and its slowness and seemingly hundreds of configuration options that I didn't care about. It was like they were trying to fit every possible feature into the software. Then I tried Phoenix and it was so much more pleasant to use, even at that young stage. I'm happy to see Firefox has survived this long and remains, for the most part, as great to use now as those early days.
