But how much more expensive is buying a second controller compared to getting a set of AA batteries, an external battery charging pack, and so on? 10-15 bucks? And the more controllers you have, the more you have to plan and rotate your charging. Instead, with the PS3 you just get 2 controllers, and you always have the choice to play with one while the other is charging, you can hook up one on the USB for a while when you're playing with two at the same time and one controller happens to run out, and if you're on your own even with just the one controller you won't need a separate charger, but instead you can just leave the PS3 controller on the USB port while you're not playing, or while you're playing, or hook it up to another computer or PC ... heck, I wouldn't be surprised if you could even charge the PS3 controller by hooking it up to a 360.
