When you think about it, one has to wonder why the OEM didn't think of this themselves...it makes so much sense!
It makes perfect sense to me from a 'manufacturing model' standpoint. The way they went about it, using
COTS parts (Commercial, Off The Shelf), has proven advantage in the classic
'make or buy' decision. To make such a regulator opens up all the same issues Pipes (and others) face, design, procurement, assembly, test, and so on as opposed to just buying the 8.5 Volt supply they did, marking it up appropriately, and offering it to their customers who are interested.
I'm quite confident they did in fact consider such options, and for solid (to them) reasons went the way they did.
To have gone this route, they would have had to put a larger, more expensive charger in every Solo (to support PA mode for those who would later want it)
raising the total price for everyone, something customers would object to if they knew?
Capitalism has given us another option in the market (hopefully), perhaps more than one in the end. This is, IMO, a good thing for customers. Choices in the market are good for us in many ways.
