I think you mean "digitizer", the interactive film used to enter information. Theoretically there are no problems. I am on my second in two years. Obviously the new (and otherwise wonderful) Palm digitizer is not all that robust.
I have lookat at others and keep coming back to Palm, which may be my stupidity. My next plan, however, is to go get a glass digitizer. From what I hear, they are more robust, if more fragile.
As for stopping entirely, that rarely happens all at once..usually it begins with a dead spot or two and expands, so you may be in luck. There are a few posts strewn about the net suggesting that unplugging and replacing the digitizer will fix problems. You might want to try it. Otherwise, you may also have screen issues (if you get nothing.)
