Apple has long touted its laptops as the top performing notebooks regardless of OS. The second-generation PowerBook G3 (the so-called Wallstreet design), released in March 1998, continued that mantle while ushering in a lightweight, curvy design that moved laptops away from the then-entrenched squared-off IBM ThinkPad aesthetic. Two subsequent variations -- the Wallstreet II design of August 1998 and the Lombard design of May 1999 -- continued to push the lighter and thinner envelope while boosting battery life. For the Mac community, the second-generation PowerBook G3 marked the shift from the desktop to the laptop as the primary computer, and arguably pushed PC laptops along the same path. These PowerBook G3s remained in use for nearly a decade.
