Over the last three decades, the Mac has morphed and evolved into a dizzying array of form factors. While some models quickly came and went, others became iconic machines in their own right. So, in honor of the Mac's 30th birthday on 24 January, here is a look back at the more influential, significant, and notable Mac machines released over the last 30 years.
Released in May of 1994, the Apple PowerBook 520 was the first laptop from any company to feature a trackpad instead of the tried-and-true trackball that, up until then, was a mainstay in laptop design. What's more, the PowerBook 520 was the first shipping laptop to come with built-in Ethernet connectivity. All in all, a forward-thinking machine.
