Power8 is going to be big deal, ibm is finally being serious about low end and competing with Intel. They are making open power consortium, tyan(server mobo maker) and nvidia already joined. Ibm needs to sell power8 in volume or else they must sell of their fab. And powerlinux is what they offer in low end. Gonna be interesting.
I wonder if this will ever spill out of enterprise server-class and into the mobile and desktop?
Mobile, probably not. But maybe Tyan makes some workstation-class motherboards, so it will maybe be possible to build an workstation with Power8. It will of course run only Linux, for AIX and IBM i, you need PowerVM, which will probably require expensive IBM-made system.
Let me backtrack on that, Open Power Consortium announcement said something about ARM-style licensing, so while the full-blown Power8 is unsuitable for mobile, a 2-core or 3-core Power7 derivative on thinner technology process might be licensed to someone who might then make CPU for some Android tablets or something of that sort.
So it is possible, IBM needs to make chips, any chips, to keep East Fishkill plant viable after 22nm shift.
