Personal belief: Linux on POWER will eat everyone’s arseholes in the enterprise side of things in the next decade.
Maybe They've had a few wrong turns with POWER over the years. The RS/6000 was just the right machine at just the right time but they stuffed that up by having a weird homebrewed unix-alike as the OS. I can attest to that personally as I had hell porting our product to it that I had just ported from PC/DOS to SunOS, Apollo Domain, and the completely different Convergent NGEN machines with not too much pain. That, unfairly, set the POWER machines back. There were a hell of a lot of PowerPC chips sold, both desktop and embedded but with the same architecture under the POWER banner they didn't do nearly so well, in part because they went down the too superscalar, too long a pipeline route that everybody else did at the same time. The result was falling behind in price/performance in a way that made them unattractive unless you were already an IBM customer. I don't know of they have recovered/will recover from that.
