I'm really bummed that Razer discontinued the Nostromo. I use my Belkin N52te constantly and wanted to get a Nostromo but Razer killed it before I could get one. Now they're selling for stupid prices on eBay. I'm an illustrator and use my N52te for more than just gaming. I use it CONSTANTLY in Photoshop and Modo. The Tartarus is supposed to be the "updated" version of the Nostromo, but the removal of the mouse wheel in favor of the addition of one extra key was just a boneheaded move. I would love to see the Nostromo brought back with the mouse wheel that the Naga has, mechanical switches, wireless capability, and maybe Chroma customization.
