It feels so good to be able to use a proper three-button computer mouse with a physical wheel! No more accidentally scrolling in while trying to open pages in a new tab; no more fatigue trying to hold it without accidental scrolling; no more wrangling in Skyrim!
At least the SuperDrive is considered a generic drive.
For some reason I decided to reboot after wiping all partitions. The laptop immediately downloaded the original Lion version of the recovery utilities and offered me to reinstall Lion, not Mountain Lion. Maybe a downgrade is in order?
