So many have tried (and failed) to recreate today's complex controllers on a touch screen. Even Sony's own PlayStation Certified tablets have on-screen buttons. It may be sufficient for a game of Final Fantasy VII--but not so much for the more demanding PlayStation games on the platform.
Thankfully, that's changing today. The Sony Tablet S has received a firmware update that allows you to connect a DualShock 3 PS3 controller to the system.
According to Engadget, in order to sync the controller to the tablet, you'll initially need a USB adapter cable that pairs the two devices. Once they're synced, you'll be able to continue using the controller sans cable.
While this feature is likely to appeal to a very limited audience, it's a good step forward for the PlayStation's growth on the Android platform. Hopefully, future PlayStation Certified devices will have this feature built-in.
