This topic comes up occasionally, and I have no idea of the answer:

. . . How long does it take a DP to physically wear out?

I'm not talking about becoming obsolete -- that's a function of how the market develops, and how one's taste changes.

But for the people who have actually used a DP long enough so it didn't work reliably any more, or the key action changed because of hundreds or thousands of hours of playing:

. . . What did you have?

. . . How long (in years, or hours of play) did it last?

Thanks --
