No, never overclocked and no hardware issues.
The worst thing I had until now, was to use once the trick of plugging the charger cord while re-inserting the battery to unbrick it.

I took care of it, as I do with all my items (it had always a screen shield and the ugly rubber case), but since Dec. 2009 it lived well, saw many countries, experienced various tough conditions between -30°C and +45°C, felt some times on the ground, so what if it died at a normal age for a hero?

However, I now feel sad and lonely.

It's hard to compare with your case, as in mine, it's the first time (and seemingly last time) that it happened.
