Formatted drive and did clean install (scary! I debated "Archive and Install", but wanted a clean slate…).

Swaps through three discs. Takes slightly more than 30 minutes to install. De-select any languages you don’t plan on using to save space. Same goes for printer drivers.

System is zippier (of course, without any extra cruft installed yet). Font anti-aliasing seems smoother — sites now look even better in Safari. Expose is awesome — I’m using it with mouse gestures (you set corners of the screen). Can also be set to use different buttons on a multi-button mouse.

Finder is good. Mainly single window, quickly skip between shortcuts. Means I won’t add folder shortcuts to the dock.

Single word to describe everything: smoooooth
