when the iMac first debuted jobs mentioned that the "i" stood for internet, but it was rarely (if ever?) mentioned in promotional materials. since that time it has become, for lack of a better term, a branding element.
[edit]
i should say the i was never explicitly mentioned as standing for the internet, but the original commercials focused on the iMac's ease of connecting to the internet. the whole "there is no step 3" thing.
Really? I always just took the "i" as a ownership thing.
