Patents like this really make you think about some of these older technologies that are everywhere...
Yep, and it also makes me appreciate it when a technology doesn't change, too, in some cases. I mean, if the change doesn't add value for *me*, I probably don't want it changed just cuz it's cooler.
I can use the same audio plugs and cables to hook up my dad's stereo or mine, even though his is 20 years older. I don't have to keep track of special cables, new kinds of cables, or buy adapters.
MIDI cables is an example where the devices could be a lot smaller, but it's worth it, to me, to have a device I can use with standard MIDI cables. The size difference ain't worth it.
I would like to see smaller, more secure connectors for FireWire or USB. As an non-pro musician, I don't like how easily my FireWire cables can be yanked out.
So, there are balances to think about. Is it worth the benefit to change the size of the headphone jack? I'm not sure I see a benefit, for myself, but I see how it benefits hardware makers.
