Firefox 3 is really what they say it is. Fast, efficient, and with a few new features to boot. Mostly the enhancements are under the hood with the revamped Gecko engine, making XHTML developers like myself uber happy.
The first thing that hit me was the speed. This little guy can really chew them pages up! I browse the GP32X forums, keeping myself up-to-date on the Pandora console, and speeds become an issue when you start opening 8 or more tabs at once. To demonstrate the difference (which is substantial), I’ve done up a little video. It’s nothing fancy, just the two browsers, one run after the other. The screen capture software actually makes my computer appear (and at times act) a little slower, so imagine a 110%-130% (guesstimation) speed increase as you watch this.
