Practical but...
I was on the fence about going wireless: on the one hand there are 2 fewer wires, but you still get a wired keyboard! And yes, if you want to boot into F8 or F2, the hardware isn't detected in time... Having said that, I don't regret my purchase: silent keyboard and mouse, no more clack-clack-clack or click-click-click (it's confusing at first, but it's nice all the same).
