I own the older model of the n52 Nostromo, and used to use it regularly, but i really havnt found a use for it as of recently, i also use an Xkeys Pro, but only use about 10 keys off of it, i have yet to find a full use of all the available keys just yet. But they do make life easier when you do need them. I want the enw n52 to replace my old one becuase it will then match all my neons and lights in my room and on my alienware boxes.
