On Tuesday, Oct. 14, Apple will unveil the latest addition to a long line of portable computers that dates back nearly 20 years — to the ungainly, 15.8-pound “Macintosh Portable” that PC World named the 17th worst technology product of all time. (link)

Apple’s notebook offerings have come a long way since 1989. They now outsell Apple desktop machines by nearly 65%. In Q3, they accounted for 29% of Apple’s AAPL total revenue. (See All eyes on the MacBook.)
