A year ago I bought and loved a Realforce 87U with Topre switches. Then, a few months ago, I setup a standing station around my Mac Book Air and borrowed a friend's Matias Quiet Pro and used it, switching in and out with my Unicomp -- and using those other boards (neither of which I find perfect) makes me type horribly on my Realforce. The tops of the Realforce caps must be smaller than the others. It's so bad I had to take the Realforce offline and move the Unicomp down to my main workstation.
Now, I am a man without a one-loved switch. I have a Das with Cherry blues. That's not the answer either.
I am sad.
