One set of my computer towers is about 5 feet from me, in front and to the side of my work desk. I had a "D'OH!" moment last week - why am I always walking around my desk to plug/unplug USB devices and SD cards? So I ordered from Amazon a 3 port USB 3.0 hub that also has a SD card reader that can sit on my desk, along with a USB 3.0 extender cable to connect it to my main tower. Of course this means less of a workout, so will have to up my walking/gym time .
Adapters are cheap at Amazon.
