No, we have a 3-5 year warranties on some products.  If those caps go we'd go back to the vendors and they'd feel the pain....

It's obvious that most electronics today are built around planned obsolescence, with the cycle sometimes as short as two years (like cell phones).  Could it be that this thinking has also invaded the manufacture of the SMD parts themselves?  After all, it all gets thrown away at the same time, so why put a component designed to last for 20 years into a device that will be binned in two?
