Virtually every single issue with the Nexus players Ive seen so far are either directly caused by user frustration e.g. mashing things or doing something stupid, or have extremely obvious workarounds or aren't really performance intensive (like the cue bug you described).
Im not saying there arent bugs in the software (or defective units, as it seems with some of the hot cue issues), but calling the decks "unusable" is just asinine.
Besides, there's a difference between: "these players have issues and warrant inconvenience, I, as a customer, demand that these issues be addressed." And the average "report" on the Pioneer forums: "FUCK YOU PIONEER AND YOU SWINDLE MY PLAYERS UNSUABLE FIX THIS SHIT OR I BUY DENON. PIONEER SUPPORT IS SHIT YOU SELL OUT TO MAKE KIDDY TOYS AND PROFIT." One is a constructive complaint, the other is an illiterate foreigner's attempt at venting that just adds excessive tension to the issue. Banging the drum and shouting at Pioneer isnt going to get anything done faster, but actually constructively finding workarounds to the issues and dealing with it can go a long way.
