> Or, more accurately, Linux stopped Unix in its tracks Thats hardly true. When Linux was ramping up steam the Big Iron companies were the only real option for stability and performance. Also for years the largest sites on the internet ran FreeBSD, not Linux. What killed Big Iron was the cost, pure and simple; its much easier to scale horizontally with lots of smaller machines than piles of giant machines. We can thank open source software and operating systems for that. To some extent, Microsoft also helped kill Big Iron as well. The advent of IIS and SQLServer made it possible to do real work on commodity hardware. PC Graphics advances killed the high end Unix Graphics workstation business too. TLDR; Linux only contributed, its not the cause.
