I have begun the search for the perfect keyboard for my dream rig. I was originally thinking I liked my macbook pro keyboard (Q3 2008), but I now find the keys a bit too hard to push down. That being said, I measured (using assorted coins because I suck) the weight required to push down a key. I do not know what keyboard model I have, but from the wikipedia article on apple keyboards, it seems it might be the A1243.
I used: 7 Quarters,
2 Nickel,
1 Dimes, and 4 pennies. Finding the weight of each coin here:
http://www.usmint.gov/mint_programs/circulatingCoins/
Q=5.670g, N=5.000g, D=2.268g, P=2.500g
The total comes to
61.958g for the peripheral keys (command, fn, alt, etc.) and about 1-2g more for the letter keys.
EDIT: The actual process was Holding the weight at the keys equilibrium position, and releasing it. At lighter weights, the key would not initiate, however if already down, it would not rise.
Making sure the center of mass of all my coins aligned with the center of the key was the biggest issue, but I tested the stack enough times to be sure this number is within 4g of the actual weight.
Well, the search continues for the perfect keyboard. 60g is too much for me, I'll look through the thread for anything lower.
