Searching for the perfect Photoshop experience, I've found a peripheral to lust after. Designed for power gamers, the Nostromo SpeedPad n52 offers a smattering of 14 custom-programmable keys, a scrollwheel, an 8-way gamepad, a fire button and a thumbswitch.

There's nothing in the site that gives any hint that these might be useful for anything other than hardcore gaming, but to my mind the equipment that hardcore gamers use is usually more than up to the task of more mundane applications like Photoshop and BBEdit.
