Firefox kicks ass
Got my issue of Wired yesterday, and their cover story is on Firefox. I hadn't thought much about switching from IE, but it's the fact that it's now become the default and that it didn't suck too badly that kept me with it. But my girlfriend downloaded it earlier today and loved it instantly, so I decided to give it a try. I can't imagine using IE again anytime in the near future. Firefox is faster and easier to use, and that opinion comes after about 3 hours of use while recovering from the below-mentioned wisdom teeth extraction.
Give it a try--it's a small download, and a really quick installation. Open source has certainly gotten it right with this one.
