As for the iMac...
... I don't believe the iMac outsold the Commodore 64's 17 million (based on Commodore's 1993 Annual Report). The iPad certainly did... in fact, in the fourth quarter of 2011 alone, Apple sold 15.4 million iPads. In that same quarter, Apple sold 37 million iPhones, for a total of over 52 million iOS devices: more units than all Macs sold in history. Taken as a country, Apple rated the 90th most wealthy based on GDP/profits... and that was last summer. Good news if you're an iOS fan, but it does illustrate, now about 19% of profits, just how expendable the MacOS is.
