So Im sure that has been brought up before, but I had trouble searching for it so here it goes. I see on a few of the manufacturer websites for cartridges that there are recommended lifespans for the stylus which can rage from 150 hours to 300 hours... On top of that I have also seen that when people are selling used tables saying that it has "XYZ" cart on it with only 75 hours or playtime etc. So here is my question....are there really people out there that count the number of hours that they have used a stylus? "whelp....one more hour of playtime, better add a tickmark to my notebook for runtime..." I mean if people actually do that cool....but these numbers that people are thowing out for hours on a used stylus have to be estimations right? FYI....Friday afternoon and bored at work...these are the thing that I think about.
