Ok, i know this is from IBM's Marketing department but it does a good job of describing the differences between a unix (or a pc) and a Mainframe system. Its not the processing power, its the IO bandwidth. A PC or Most Unix boxes aren't even close. i'm not saying its the end all be all of computers but for what its used for, Lots and Lots of Transactions and no downtime and thats 99.9999% uptime. http://www.s390.ibm.com/marketing/gf225122.html
