You would, as a logical next step, expect Sony to release PC drivers..
It was nice when MS supported the wired controllers in windows, and now they have the wireless receiver for the wireless stuff, PC gaming just got some quality controls..
I personally hate the Sony controller, but that's just down to me and the ergo's.. I've always hated the PS1/2 pads as well, I had to go and get 2rd party designs to stop my thumbs falling off!! so I would never want to use it on a PC, but I understand plenty will do!..
