Don't you have anything better to do with your life than yammering away on the minute details of a keyboard? I have both an M and an F that I picked up at goodwill for nothing 15 years ago and for the first time yesterday I googled about them and found 'enthusiast' (here an euphemism for retarded) websites where idiots bounce off the walls telling each other about the orgasms per second they have when using them.
And 'using' is an overstatement with 90% of those morons. Most are busy opening them, cleaning the last atom of dirt off them, 'restoring' what doesn't need any restoration, 'upgrading', thinking of names for them, 'modding', taking photos, showing them off, in general jerking off about the clicky sensations and the superb accuracy of their typing and other general uber-dorkiness. What I never found there was anything useful to do with them, ie. actually program a computer.
Go type 'messenger lectures' in youtube and see what smart people look like, then kill yourself disassembling your One True Keyboard (TM) for the nth time and swallowing all the buckling springs.
And then mail one of your remaining model Fs to me.
