"when missing the most basic functionality " A DAP's most basic functionality is playing music. " I have only just bought the X5ii and it was obsolete before I even received it," If it didn't have any outputs, that seems like something I would understand. You seem to be very salty over this. In fact, all you have to do is make a playlist with the songs you would want to bookmark. From my seat it looks like you are greatly over-reacting over an issue that could be quite easily solved if you took a couple minutes of your time to help yourself.
