Re: Dunno, Man
If you had a blank slate - i.e there were no existing 3.5mm devices on the market - would you use the same format today?
I've had MiniDisc players that have developed faults with the 3.5mm jack (fortunately they had a second audio-out 3.5mm port at line level). I've had an early-ish Creative Labs MP3 jukebox fail for the same reason, because the port was soldered directly onto the main PCB. I've broken lots of headphone cables by snagging them on things - the failure occurs by the plug. I've had a Sony Xperiaphone where the Tip Ring Ring Collar was not sufficient for them ('cos you only get mono in) so a TRRRC 3.5mm port was used in order to support stereo in (for noise-cancelling headphones that used the phone's silicon, and for stereo microphones).
