Mainframe computers are used by many of the largest companies and government institutions. This paper reviews the technology of mainframe computer systems and describes potential, lower-priced alternatives. The forces that maintain and expand the dominance of IBM in the mainframe market are explained.  The paper also presents evidence that market dominance has led to a slowdown in innovation in mainframe technology.

I agree, but now that HP has started to compete with IBM i think innovation will follow.

It really costs a lot of money to operate and maintain a computer system mainframe. There's a big reduction in hardware price, but the software cost isn't. I hope that there'll be a time when alternatives surpass the current mainframe systems.
