In my discussion of Steppinrazor's UI, I made note that I was not privy to the Nostromo, having never had the pleasure of resting my fingers on its keys.
The Razer Nostromo is a peripheral that acts as a keyboard for input commands, with buttons for clicking, a D-pad, a scrollwheel, and much more.
Back in July, I featured a submission on Reader UI of the Week from reader Steppinrazor which featured a dual-peripheral setup of the Razer Naga MMO mouse and the Razer Nostromo.
