Also in this vein: try explaining to your bosses why spending money for an AC adapter for a USB I/O device in a business-critical piece of hardware that does not tolerate lost signals well is a justifiable expense when it is perfectly capable of getting power from a USB cable into a computer that is already powering entirely too many things.

I actually bought it myself and smuggled in the upgrade just because the headaches it would cause me, personally, weren't worth it.
