The only use for this is an environment where you don't have network access but need to transfer multiple GB of files. This happened where I used to work where a lab was isolated from the company network, but we needed to load multiple-GB builds onto the hardware. Add onto that the fact that we needed multiple builds for different situations, and transferring that kind of data any other way was unfeasible. And no, eSATA wasn't an option. Yeah, it will be nicer with USB3, but the need for lots of storage and the USB protocol is here today, maybe just not as much of a daily user as most people would like.
