Why is it that almost all flash drives now have no removable protective cap? When I carry them in my pocket, they get lint (or worse) in the USB connector. The slide (retractable) type offers no real protection. And it's even hard to find the swivel type, which does not offer much protection anyway. Some flash drives do not have any type of cover over the connector, you just plug them in and play. This is an advancement? Another design change which results in an inferior rather than improved product. I suspect the explanation is that it benefits the manufacturer somehow. Kingston was manufacturing drives with a removable cap, but the cases are so fat now that I can't plug two of them in next to each other anymore.
