Reasons why IE is better than Mozilla.
1: Mozilla has the worst looking grapics and icons of any browser I have ever seen. By a mile. (Well, maybe some of the 'nix specific ones are worse, but not that I remember.)
2: Although Mozilla has now copied Opera's tabbed browsing feature, it still has the worst multiple window management of the big three. There is still no way to open a new window or tab in the background (which you can do in Opera) or at least have it open in a smaller-size window which is easily clicked to the background (IE).
3: Mozilla wins the clunkiness war by a huge margin. It still has difficulty with sizing tables quite often. (Well, the ones up to RC 2 do, have yet to test with 1.0.)
4: Although vastly improved over the 0.9x versions, (at least on the Windows platform) Mozilla takes the longest time to load of any browser. (Actually, IE almost certainly takes even longer, but because Bill wants it this way, you have to wait while IE loads during Windows boot whether you want it or not. Unless you run 98Lite, of course.)
5: Once loaded, Mozilla is no faster than IE, and a lot slower than Opera.
There is no way I'm goning to be able to think of ten reasons, so I'll just have to stop at 5.
