Very, very tempting. But it's beta, so I'll stick to FF for now.
Speaking of which, what will happen to FF? With chrome's new JSVM (inc. compilation to bytecode!) and other awesome features, I can't see there being much need for FF. :S
Something I'm not digging about Chrome: the reasonably small (esp. on my resolution? 1680 by 1050) to hit close tab button.
