The developer toolbar mostly. I do a good amount of web dev so its helpful. Taking pdf screenshots with a single command has come in handy. Also the 3D view is gimmicky but pretty awesome. Tab groups is another favorite.
There still seems to be some sort of memory leakage though. I have to shut down the browser every so often to clear out the 3GB of ram it suddenly decided it needed to have.
