it appears HP are making some new kind of computer and creating a new OS for it... http://www.technologyreview.com/news/533066/hp-will-release-a-revolutionary-new-operating-system-in-2015/
maybe this could be the new platform for AmigaOS
Early prototype in 2016, that should align nicely with the release of AmigaOS 4.2
What HP are doing is more important than what they produce; They are looking at what compromises have been made in the past and are questioning if we still need to be making them. This is a key mindset for innovation.
Server computing is where companies spend gazillions of $ each year and makes sense to launch to these customers, most of which are dealing with power consumption issues for their ever demanding server loads.
Personal computing is migrating over to the personal devices like notebooks, tablets, and smartphones. Even in the corporate sector here in Oz most companies issue a notebook to their staff. Denizens of desktops seem to be developers, gamers, and professionals in the video and CAD/CAM segments. Oh and the nouveau-retro Amiga hobbyists.
It's all a moot point anyway. Until someone decides to open-source AmigaOS 4.x we are stuck with PowerPC. More like MoneyPC.
