I'm Typing this on a rubber dome on campus, between my classes. Its a mac one, came with an iMac.
In that one sentence above, I actually managed to make an error on EACH word, and failed to hit the space between every two letters.
The plain and simple fact is that rubber domes do not have a good lifespan associated with them in hard/prolonged usage. I LITERALLY have to smush each key HARD to get it to actuate it right now, due to all the stresses this keyboard has lived through. Granted the keyboard is significantly more quiet than my Das Silent, but that's attributed to the fact that there's so much key friction in the keys its slowing ALL movement. Actually even to that point, it takes a bit for the keys to spring back up... The keys are mushy, there's no sense of tactility at all (not even close to linear, just... bleh.), the dome is so degraded at this point that there's no tactile point left (you can press slowly, and feel the mush slowly give way...). To be absolutely honest, I think sticking my finger through a bowl of jello would feel better than THIS kind of mush. I think even the Rip-0-meter would fail on this keyboard, the stack might get so high they would topple before the key pressed down (its not isolated to this board only, the entire row of them in the library are this bad)
The best keyboards on campus are obviously the newest ones, and even then those are Dell Scissor switches.
At home I hated the rubber domes for ages, well before I even learned what a mechanical keyboard was. Not really mushy, but I did not like the key travel. The only thing I did like was the double tapping, as you could manage it without really lifting your finger at all (which theoretically you can accomplish with a red or black as well). Scissors were my next stage in keyboards (last two years), but that didn't live exceptionally well, as I had C and M key failures; not to mention the key press limitations were very restricting in what I could accomplish in MMOs, or certain command combinations I changed around for ease of use in programs. You really don't need NKRO even for that, but at that point 6KRO is still light years ahead.
I have to be perfectly honest here, I'm actually getting a typing cramp for the first time in my life. This rubber dome is absolutely HORRIBLE. I have used significantly better rubber domes than this one around campus, but they don't get much better (scissor switches aside; as they are actually serviceable for me. I like them as well, but not as much as Cherry Browns). Once you use a well broken in mechanical, any rubber dome loses out significantly on feel and precision (in store demo units don't get enough usage, they barely feel different from a new rubber dome). It is a noticeable and drastic difference in key travel, tactility and overall feel that can be seen within 2 weeks of usage.
