I have used that and it seems to be slower and have fewer options, but as far as lean I would probably agree.
Really?! Right now, I'm using Firefox 1.5 with 3 tabs open (including Yahoo! Mail Beta) and itz only using 62MB, as compared to IE 7.0 with only 1 tab open using 78MB. This is on a 3GHz Pentium 4 (Dell) with 2GB of memory running WinXP Pro SP2.Are you kidding? Firefox uses about 4x as much RAM as Explorer will. Firefox really does make a difference, and I believe that it uses more RAM if you have more RAM for optimization.
