I just got my 3rd Realforce today from elitekeyboards.com. I have two 86U, variable weight, keyboards already (one black, one white), but I wanted the 87U for the caps lock light...weird huh?
Also ordered some colored keycaps, to mix it up...


Little bit closer look at the keycaps, nice


Used them all up, to get my money's worth haha

I was using the white 86U on my linux desktop at work, so I swapped that with this new one and am now at home with the white 86U from work. The silent feels very similar, but much more quiet... the extra silence is the key release sound, not the down. It might be mental, but this extra silence makes the silent 87U feel even more solid to type on than the regular 86U's. An even improved topre "thonk" perhaps?
BTW, my reason for liking the variable weight realforce, I like the 35g key for my left pinky finger... I broke my left hand a couple years ago, had some retarded surgery, and now that pinky is weak. Otherwise I'm not aware of the difference in key weight while typing, for either hand.
Before I got this I had my Filco MX red keyboard on my mac mini and my black 86U on my home linux desktop. I switched between those often and went through phases on which I liked typing on more. Right now I'm definitely in a topre phase, all 3 of my desktops (1 work; 2 home) are realforce now, and I'm loving them. I'm a unix admin and type all day long, so that's why my new favorite is at work now, I miss it and look forward to tomorrow morning so I can type on it again.
