All my headphones have 3.5mm jack, and that's why I want the 3.5 jack, I guess.
it's usually pretty easy to snap/screw on a 6.3mm adapter over the 3.5mm jack...and much smaller. the 6.3mm->3.5mm adapter is much bulkier (example: grado's 1/4" to 1/8" adapter)
i think since more use is via desktop/home (based on current poll numbers), a 6.3mm jack would be preferable...my 2 cents.
