The new Model Fs feel just like my original Model Fs if you have ever typed on one. Typing on Model Fs feel a bit lighter and crisper than on a Model M. I loved my Models Ms and I have had one since I was a kid, but once I was using a Model F, the M felt like a rough imitation (which I suppose isn't that far from the truth). It isn't the world changing difference that some people would tell you, but it does feel significantly better to me. It doesn't hurt that you also get NKRO and, in these reproductions, the ability to customize the layout via the programmable firmware. I also really like the hefty case compared to the plastic of the Model Ms, especially the zinc case in the classic model, but the aluminum case of the FSSK isn't too shabby either.
