An audio player that played proprietary files by exactly one record company would be obvious bullshit.
Somehow publishing has allowed itself to be squeezed into the e-reader equivalent. The result is a predictable lack of quality in both hardware and software - never mind consumer choice and delivery options.
What you all guys mean by Kindle? I have one for like a decade and I don’t get it. It’s not a strong brand of itself like iPhone (which is also smartphone).
All I can tell about it is that it’s a mediocre reader and that’s it. I don't upgrade it to any other reader because it just works, so I’m going to keep it till it won’t.
