I've just installed the Firefox 2.0 browser, and my initial reaction is; "oh, my god, this is good!"

Initially these are the key points I like the most: 

• It installed fast and without rebooting.
• It handles rss-feed as any other page
• It "remembers" all tabs, so if you close one by mistake, you simple re-open it!
• It seems VERY fast

I thought about upgrading to IE7.0 as well. It would be nice to have a benchmark competition.
