I wish the industry had moved to 2.5mm back then. 3.5mm is great, it has survived the test of time (introduced in 1964!) because it is so good, but 2.5mm is only better than 3.5mm (except for the manufacturing and migration costs).<p>If the industry had moved to 2.5mm back then, Apple and Intel and the DRM-lobby would have had one less excuse for phasing out analog audio ports today.
