--All my Macs have had USB ports, or am I, besides being computer illiterate, thinking of something else.--
The first was the 2001 USB ibook which had not one but TWO USB ports as the ad went (my pc at the time came with four). Interesting that mac came out with the USB ibook simultaneously with the IPOD which was USB leaving existing mac owners complaining why they couldn't plug the IPOD into a mac!
The iMac had USB ports in 1998. The first generation iBooks had it in 1999, as did the bronze keyboard Powerbooks that year (actually they had two USB ports).
You must just be talkin' about laptops???? Cuz my first G-r had USB ports.
