alt Hacker NewsBack in the day I worked for the makers of Yellow Dog Linux, and I think because of these scarcities we had a pretty good model of buying Apple Risc hardware at OEM prices and putting Linux on them, mostly for university scientists but also for enthusiasts. There was a lot of work keeping Linux running on hardware created by a company that was ambivalent about having alternative operating systems on its hardware, but it was fun and a great group of people to work for.
I recall Yellow Dog, probably because of the PS3.
The big thing most people from outside the Acorn era of Arm are missing here is the Risc PC never had decent floating point support. For pure integer stuff the StrongArm upgrade was, at lauch, simply astounding, but floats . . . nope. (The StrongArm upgrade merely needed to be in the slot near the vents too, it had no active cooling or even a serious heatsink).
Oddly the later lower end A7000 came in a A7000+ variant which did have an FPU, probably because Arm needed to test their FPU out somewhere.
