The Windows beta of Safari is a steaming turd of a browser.
I use firefox on my desktop and IE7 on my laptop. I'm not as taken with the anti-microsoft bias as a lot of so called 'experts' in the field. I'm smart with my browsing habits and my computers are adequately secure so I'm not concerned with IE being open to attack.
I'm like Ice, I'm a freelance designer (I can use that tag now, as I have a few paid websites close to going live :P) so I use all the browsers to test for compatibility and iron out bugs. If I had to choose a favourite, it would be firefox for its expandability. Fucking great memory hog though.
The greatest delight is to mark one's enemy, prepare everything, avenge oneself thoroughly, and then go to sleep.
