The Macintosh already enjoyed its silver anniversary this year, but it's not the only Mac product to hit a milestone in 2009. Twenty years ago this week, Apple introduced its first laptop computer--the Macintosh Portable.
At $6,500 (that's $11,313 in 2009 dollars), 16 pounds, and the size of a briefcase, it failed to realize the dream of the perfect Mac laptop. But a lackluster reception didn't hold Apple back for long. Having learned from its mistakes, the company rolled out its PowerBook series just two years later--a release that offered more innovation and influence than Apple's then-low market share would suggest.
