Magnetic bit holders are great in clean work environments. But, at my work, the retention spring is preferred. The magnetic holders pick up steel wool dust like crazy. That stuff then makes its' way into the tool pivots.
I demagnetize my EDC MTs regularly for that reason. The bits being magnetic instead of the bit holder might possibly be a solution. That way guys like me can buy non-magnetized bits to use in a spring retention bit holder. And the guys who like magnetic bits can use magnetized bits.
I definitely prefer a system that doesn't require a medium(ex. slip on adapters).
When I need something aside from a phillips or flat head, I pull out the default bit and get the one I need. When I am done, I put the odd bit back in the sleeve and pop my default bit back in so I don't have to switch for regular screws. Pulling a two-sided bit out and turning it around is just as easy as folding one driver into the handle and unfolding another.

Demagnetize MTs?? Sounds quite interesting, how do you do that?
Re retention, I'd tend to agree magnetic might not be for everyone (magnetic cards are definitely at risk - heck, my phone, that does not contain magnetic mounts, scrambles these) so some form of spring retention would be the alternative in order to reach a larger user population. I hear you regarding the extra space required. However, Vic's solution with a sprung retention ball in the bit provides for a space-saving solution. Would that be an option? As an alternative I think one could also design the holder to have a spring... Do you have pics of what you are intending to build?
I appreciate your consideration of everyone's input. Can't wait to see what you come up with, Vidar.
