Very clean-looking keyboard! Can you compare the stiffness of the switches versus some other mechanical keyboards you've used before?
I would put it between a stiff Model M, and a light Model M.
I don't know if you have used many model Ms, but there is a clear difference between certain models. The older ones (silver label mostly) have a very precise and medium-light action, then you have some (not all) of the later ones with a heavy actuation. I love the feel of the lighter touch Model Ms, and I dislike the heavy ones.
I would put the actuation of this M0110 in between those Model M springs. I have a Made-In-Japan M0110A with Mitsumi switches and the Mitsumi switches are significantly lighter than this M1010.
I also have another M1010 that I haven't converted yet, and I feel that it is also lighter than this one (though not by much) The only difference I can see between this M0110 and the other M0110 is that one has 2 rows of drainage holes on the bottom, and the other has only one row.
I need to get a scale so I can measure the key weight more accurately...
