My biggest problem with the new switch is that it uses rubber. So far Cherry switches were really, really durable. A good mechanical keyboard lasted long years even with very heavy use. Now I guess this will change. Rubber ages.
Though, a Blue switch keyboard will also get much "weaker". My original Blackwidow lasted me about 3 years before the keys became mushy. It used the original Blue Cherry switches.
@DSTARR3: On Brown, most people don't bottom out, because the click helps you not to. But on the Red, you have no feedback. So most of the time you just bottom out. And this is why Red becomes so loud - sometimes even louder than Blue. Of course you can just "not bottom out" but it is very hard to do, and well, it's a pain.
I tried O-Rings, but they changed the feel of keys totally. So my comfortable Red switches became totally membrane like. So I don't think they are a good solution.
tl;dr: I am skeptic about these new Silent switches.
