I have come to the opinion that NOTHING electronic lasts! If the thing lasts 10 years it is remarkable.
Even the liquid-crystal dashboard on my car is dying, and no-one wants to repair it.
Look at computers. You don't repair, you update. Replace parts, until so many things have failed that you've replaced everything. And now have an out-of-date box.

Sorry for the tirade, Paul, but I'm going to scrap a faithful reliable car because I can't read the speedo and fuel gauge.
