This post actually inspired me to plug in my Realforce just so I could type it since it hasn't been plugged in for a few weeks (been playing SC2 on my Filco Brown for a bit).
I use only my Linear R at work. Used to swap with my Blues for a while but decided the stress over typing with them (I'm very self-conscious of the sound of Blues, though 140WPM bottoming out on Reds doesn't bother me for some reason) wasn't worth it. I may bring them back to the office if I'm feeling saucy some day. Really don't have a use for them at home, though.
At home I regularly switch between my Browns for SC2 and Blacks for typing forums posts and general chatting on the internet (weird, I know). The very quiet sound and springyness of the Blacks is nice for late night sessions and not waking up the Mrs. I use my Realforce for WoW/FPS games primarily (though they're a pleasure to type on as well) and since I've been playing SC2 exclusively to train up for some tournies at home I haven't had it plugged in for a while.
Typing on the Realforce right now just makes me happy. Topres are something that need to be felt to really be believed. They really are special.
Anyway, I love all my boards for different reasons and am happy that I own all of them for different reasons. I wouldn't sell any of them now. Heck, I probably typed this post just to have an excuse to write a fair amount of text with my Realforce.
