I purchased mine off of eBay about a month ago and just love it. My challenge was that most of the ones on eBay at the time were special editions, rather than the original yellow one. I held out for the original and glad that I did.
The only frustration is “blue-light-itis.” The Pono has a blue light that is supposed to come on with genuine high res recordings (approved by Young, I suspect) and available from the music service that was to accompany Pono. However, the only song that works for was the one Neal Young song that came with the Pono. Regardless of format or bit rate, no external file I’ve found turn that light on.
I would (foolishly) pay a pretty penny for some more blue light music originating from the Pono library. Anyone have some?
