I use one for work and gaming, ( apple wireless keyboard ) I like it, I don't personally get the whole mechanical keyboard thing, I've used them in the past, but found out they are not for me. I highly doubt any person can honestly say "OMG this unmeasurable lag from this keyboard is so noticable and highly annoying and my gaming would be so much better with a $100+ mechanical"
I like em, they are small and compact, and are really nice to type on. and have zero complaints about gaming or working with them. ( except I wish I would have gone with the wireless one at work like i did at home )
EDIT: and the razer keyboard seems pretty gimmicky, which is fine if you like the whole "i'm a pro gamer and not an adult" look, 1 thing I noticed is the programable hotkeys are in an awkward place, basically, to use them you would have to take your hand off the mouse, which would not be ideal in any fast paced game.
The razer nostromo is great, keep one hand on the mouse and the other on all the keys you need. ( although I have mine programed for work use, can't really say much as far as gaming with it, but would imagine it would be fine after the few hours you need to get used to it. )
