My 20" 2.0GHz iMac is arriving today. (Naturally, time is passing by uber-slow today...) Besides the usual "ooh-ing" and "ahh-ing" over the unit, what are some "first" things I should do with it before I start working with it? I'm curious how others "prep" their Macs and why they do it. For instance, I recall reading a while back to do a clean install of the OS as soon as you unpack it. This supposedly would ensure that you've got an error-free OS install as well as giving you the opportunity to trim away any unnecessary "default" install options (such as multi-language support).
