I was actually discussing a similar idea the other day with a friend, but instead of having a dongle hanging off the usb port in a way that can both damage the port and the reader I was thinking it would be cooler if it was integrated into a wrap around case, the case would have a small fold up plug that connects to the micro-usb port and the internals of the card reader could be integrated into the back of the case along with one or more micro sd card slots. I would pay good money for a decent case with that integrated as a feature, maybe a battery backup as well since it already has access to the micro usb port.
