Yeah, It would pretty much pay for itself after a day and a half of working, but I've already spent so much money on my office computer set up ( $100 mouse, $100 chair, $400 monitor, $50 for the nostromo, etc. I don't get paid that much, but I couldn't stand working on the office issued equipment ( most people in the office are still working on P4's and ancient hardware that dosn't even meet the minimum requirements for autocad ) I kinda hate spending more money on computer equipment, even if it will help me out at my job.
Ever since I got my mechanical keyboard, my domes in my office issued keyboard and my nostromo feel like junk.
and If i did replace the switches, thats about $40 worth of switches ( 20 switches ) and that adds up to a very pricy device. ( though like my mouse, I would probably end up taking it to and from work everyday ) I never really tried gaming on my nostromo, since it does have a very steep learning curve. I did try it out with BF3, but it felt very weird to me. But I can see how having a custom profile for games like starcraft and such would prove very useful once you learned the hang of it. And I also HATE the way 99% of pc hardware looks, all black with red/blue/green led's, its just so ugly, I'd probably end up painting it white eventually. And lastly, I hate ordering things like this online. I'm very very very picky with my computer hardware, and if I decided I want to return it, thats probably at least $30 total in shipping thrown away with nothing to show for it.
And i've heard very mixed things about the browns, mostly that they are awesome, or feel like dirty reds. I do bottom out, and with the reds, thats the only way i knew if I had actuated the switch,
