I have them side by side (2x HHKB, RF). I have just ordered 2 brand new HHKBs and it will be interesting to see how they stack up one next to the other, but I'd say the difference won't be much. I can not tell the difference between the 3 years old and 7 years old.hansichen wrote: ↑Else I would be worriedadhoc wrote: ↑Well I can tell you for a fact my seven year old daily beater hhkb (45g) still feels A LOT lighter than my new realforce (55g).
A keyboard won't age within minutes so if it gets lighter or stiffer over the years your hands would adjust as well. A 30g>45g or 45g>55g change would be way more than I'd expect but it would be a fun thing to compare.
At 130+ WPM, my fingers actually get fatigued with 55g Topre domes, whereas I can go for hours on 45g.
As you said: 55g and 45g is a pretty significant weight change that can tire your fingers. 7 years isn't too much in a keyboard lifetime (I think at 50M actuations a normal worker would need over 20 years to reach the 50 million actuations) so I'd be very negatively surprised to see such a drastic change within this period of time. Whereas a change from 45g to 48g would be measurable but probably barely noticeable.
I guess in the end factors like storage, production cycle and other factors will have more influence on the weight than how much it was used. Either way: a side by side comparison of boards with different usage over the years would be interesting (eg a new pro 1 and a heavily used pro 1).
