I'm fine with Firefox 3 at the moment, I might give Chrome a try though just to see how it is. I know I'm in the minority but I like clutter, well organised clutter. I have loads of icons on my desktop for example, but it speeds everything up for me cos I know where everything is. Same with Firefox, I have buttons spanning the whole 1680 pixels of the screen, speeds things up for me cos I can just shoot the cursor up to where I want it.
Something that sounds great about Chrome is the independent tab rendering, I like the idea of how individual tabs can crash without ballsing the whole browser window up.
