Just bought one from there, and shipped to me last week, still testing it out, but so far liking it, feels tamer than the pro 2, at first didn't notice the loss of travel, but now that i have typed on it a little, i can feel the difference, as for whether the type s really stands for speed or just advertising hocus pocus, i need some more time before i can safely comment on that.
I am just waiting until i can get someone to help me do a blindfold/ear muff test to see if i can feel the difference between with or without type S. I wish i can get a real force low noise in for the test as well, but i can't afford 3 topres...
Oh btw i noticed people were moaning about pinging, my type S has a slight ping on the space bar, i tried taking it apart and knocking on the various parts, and the high pitch ring seems to come from the key cap itself (try hitting the key cap with the case or other key caps the noise is surprisingly high pitch)... not a big issue, but being a type S, that is the most prominent noise the keyboard makes... My pro 2 has the same problem (a much worse case of it) some time after a few weeks use of it, it lost the nice thock on the space bar, and is now giving a very mechanical sound, and its weird because the noise is made when typed with my right thumb, but not with my left thumb, tried taking the thing apart and messed with it for ages to no avail..
brief note on impression so far (only 1.5 weeks of use), feels more linear with the loss of the little bit of travel at the top, especially noticeable when typing at high speed, unlike the brown (never tried any other MX cherries so cannot compare with blue etc) the faster you type the lower the tactile, i feet that the pro 2's tactile response doesn't go away with speed, if i may use a metaphor, it is kinda like slappaing water, the faster you hit it, the more forceful the response. So the type s loses alittle bit of that, i never even realised that until i tried the type s, and then tried to compare it back to the pro 2. With all that said the difference is minimal, and it is much more accurate to say that it is just the pro 2 with less noise topping out, as expected, as advertised.
Another thing i noted, if you just run your fingers lightly over the keytops on the pro 2, it makes a noise (like all keyboards would), and i was thinking the type S wouldn't (or at least less), but it doesn't damp that noise, it makes the same noise, the only noise damped is when the key is coming up, not sure how this is relevant in day to day use, but it is something i noted.
