when there was some talk about what it would take to make a viable not-Intel platform for the data center.
Itanium is only just spinning down, SPARC and POWER have been being sold continuously, and are still being developed (even if not as much as before) and sold by their respective vendors. Neither is even that expensive compared to similar grade server hardware. I.e. if you're maxing out a Dell R740 or R7415 or an HP DL380 then there's likely a POWER or SPARC system in your price range.
The viability of that depends a lot on what you're doing. In a lot of cloud vendor cases, I can see why OpenPOWER (or any remnants of the days around fifteen years ago when there was an open source SPARC design) would be Of Interest. I suspect it has less to do with Intel specifically (although in the past few years that's probably become a bigger issue) and more with being in control of as much of the server design as possible. It's been well known, of course, for a long time that the biggest tech companies and cloud vendors aren't out there just buying the same Proliants and PowerEdges everyone else does.
But, point taken about OpenPOWER seeing some action at this piont.
In other datacenter curiosities ARM is realistically the big exciting new entrant to the datacenter (if only because by technicality POWER and SPARC never left)
$1000 is definitely closer to the curiosity range. I know Amiga enthusiasts happily pay around that much for PowerPC desktop systems and have for a while. It'll be interesting to see where you start seeing these things pop up, priced like that.
Yeah, as time goes on and, importantly, as the values and priorities of people acquiring these machines changes, it'll be interesting to see how values change.Predicting what will be valuable and desirable in 20 years' time is as much an art as it is a science.
As I mention on a regular basis, we're kind of (I hope) at the tail end of people trying to treat late MacPPC machines as viable main modern computers, so today the value is mainly in the later and higher end machines: Power Macs, MDDs, The Quad, The 2.7, the 2005/PCIe versions, and the highest end PowerBooks anybody can find.
In a couple years as it loops back around to people having nostalgia for these machines, I suspect we'll see the values start to even out as people distribute themselves between "whatever I can get" and "what I had back in the day" (which is going to be eMacs, iMacs, iBooks).
Different individuals also try to collect at different points of interest, depending on how far ahead they can see, what interest them, or what deals they're looking for.
In terms of what will stand out though? Who knows. Apple's product line contracted a lot after the late '90s and really I have yet to see interest in anything specifically explode the way it did for the SE/30, Color Classic, and perhaps the TAM or a few other models everybody seems to want.
