Ah the typical Mac fan response. It's not "Mac enough" so it sucks. It's not by Apple so it sucks.
Some of us actually choose to judge applications by their merits, not their heritage. Safari is virtually uncustomizeable and that's its biggest flaw, not how fast it is. The interface is more or less written in stone and if you don't like something about it, too bad. But I keep forgetting most Mac users LIKE that. After all, why have it your way when you can have it the McDonald's way?
I like that when I use Firefox, I can get the same great features and even the same great style looks (I like the Noia Extreme theme) when I use Windows, Linux and yes even my two Macs. It's seamless between platforms. Until Safari 4.0, it looked like garbage on a Windows machine and it still does not run natively in Linux because Apple doesn't give a crap about supporting all three platforms. I will occasionally use Safari 4.0.1, but most of the time I still used Firefox 3.0.x. So if Firefox 3.5 is faster than 3.0.x, I'm sure I'll continue to use it because it has the best interface options...namely it does what *I* want it to do, not what Apple wants it to do.
