John Siracusa writes: "Mac OS X 10.0 was released five years ago today, on March 24th, 2001. Mac OS X 10.0 was the end of many things. First and foremost, it was the end of one of the most drawn-out, heart-wrenching death spirals in the history of the technology sector. Historians (and Wall Street) may say that it was the iMac, with its fresh, daring industrial design, that marked the turning point for Apple. But that iMac was merely a stay of execution at best, and a last, desperate gasp at worst. By the turn of the century, Apple needed a new OS, and it needed one badly. No amount of translucent plastic was going to change that."
