Cobra says what I'd say. And I didn't mean all wireless devices, just most of those meant for use in the home. You're at home... where the hell are you going to go? My PSP, for instance, is always plugged in when I'm at home. I pull out the battery and plug it into the wall jack so as not to waste charge. I save the battery for when I'm on the can at work, on the subway, whatever. Away from a power source. If I play with it at my desk, same deal. Pull out the battery, plug in the wall jack. And because of the battery thing with wireless controllers, I actually find them *less* appealing than a wired controller. Again, I just don't get it. Why would you want to have the bother of having to charge it all the time, especially since when its charging... it becomes a wired controller again, meaning that its only wireless maybe 80% of the time you're using it?
