He does rock, doesn't he? 
I don't have one, and am too broke to get one, but I would imagine that it would come in handy to be able to be tethered when you don't wanna wait around for a charge. The consistency would probably be better too (no drop-offs, longer if existent cut-offs - it would be like a freshly charged batt all day long). If nothing else, think of the extra battery life when you're not tethered!
