Memory usage is amazing in chrome. I've recently been comparing footprint on exactly the same tasks with my own web app. Chrome < 30mb, IE 7 fully patched XP > 160mb, FF ~80mb. I'm still using FF as my default but may be switching soon ;)

I'm jealous of the next generation of web developers who will (hopefully) work in a web environment with lots of competition and not so much of a browser monopoly!
