On Valentine's Day. 2000, I posted this The Road Warrior piece, discussing processor upgrades for the PowerBook 1400, which was one of the most upgradeable Apple laptops ever, and one that benefited mightily from being upgraded, vaulting it into the G3 era.

Interestingly, going on nine years later, Sonnet still sells two G3 processor upgrade products for the PowerBook 1400, offering up to 12x overall speed improvement over original system. The Sonnet Crescendo PB/G3 replaces the PowerBook's original, poky 603e processor card with a speedy 466 MHz G3 processor with high-speed Level 2 backside cache. However, the PBG3-400-1M 400 MHz G3 with 1MB/200 MHz L2 cache, and PBG3-466-1M 466 MHz G3 with 1MB/186 MHz L2 cache are currently flagged "Available While Supplies Last," so if you want one, it would be prudent to move soon
