February 17, 1997: Apple launches the PowerBook 3400, a laptop the company claims is the fastest portable computer in the world.

After a rough few years for the PowerBook, this model throws down the gauntlet to rivals. It packs a PowerPC 603e processor capable of running at speeds up to 240MHz. While speedier Apple laptops will quickly overtake the PowerBook 3400, at the time it can keep up with some impressive desktop Macs.
