The only minor complaint I have about this unit is that one of the keyboard shortcuts to switch (double tap control then 1 or 2) gets in the way with many games that I play which use the control button (usually as a fire button and not always remapping). For basic computing unrelated to alien blasting or other entertainment tasks where this can be an issue, it works just fine. It appears to draw USB power from one or both of the computers connected to it, so an additional USB power cable isn't strictly necessary, although I'll leave it plugged in anyway, just in case.
