Last I checked a datacenter works in complete storage, not so much in general compute, which is whder I think POWER fits. I also thing POWER would work in consumer products if the 4 and 8 core stuff was a bit more power efficient. The problem is convincing companies that people would have an interest, and thats where stuff like the TALOS comes in, but also future AmigaONE machines, and I do see a lot, A LOT, of energy for PPC and POWER on the archlinux, gentoo, and Void linux channels on IRC. Almost evey night 2 weeks ago I was talking to people who were working with POWER machines at their work, had POWER based desktops at their desks that they wanted at home, but had little incentive to drop 4000 dollars minimum on one of the IBM provided POWER6 or 7 machines that were being sold to other companies.
POWER has a lot of potential, but using it in a storage environment and only in servers / workstations… Mmmmm, not so much.
