And to connect to your PC, you'll need this wireless gaming receiver

make sure you get the genuine one

If you use a wireless controller, you can only connect to the PC using the wireless gaming receiver. You can't use the wireless controller and connecting it to a USB via the play and charge kit. So you CAN still use the controller while charging it if you had the wireless gaming receiver though. Hope that clears up your question.

They also had a quick charge kit, but using this you can't use the battery while charging.

For the PS3 controller, I guess you can say that, yes the receiver is a bluetooth receiver (in this case my bluetooth receiver on my mac). But I'm not sure if other bluetooth receiver will do the same, I'm not sure how the bluetooth works.

Aaah you meant the ps3 controller as bluetooth, don't know if it would work at all on the pc, even when I have bluetooth, I don't have the drivers for the controller and probably alot of games won't recognize this controller either.

Just wonder how it would feel when I am in game, meaning the controller looks like it's 2 times bigger than a playstation controller, but there I only have a ps1 and 2 and maybe bigger is indeed better.

What are you guys playing on the XBox?
I am getting mine back soon

I'm going to buy Dead Island today so I'll be playing that a lot until, of course, gears 3 release!
Other than that I'm playing gears 1-2 and CoD BO

Am not playing xbox myself, but I allready played 7 hrs. of dead island according to steam, wow it's such a cool game and it's still not unlocked here in europe, even when it's after midnight allready.
