derekp brings up a good point, one that I know I've harped on many times here: don't confuse perception (created by forum posts) with reality. Typically, failures of new devices in the field amount to 5% or less of all shipped. Any more and you risk going out of business fast. Any less and you are probably spending more to accomplish that than you save in reverse logistics (YMMV).

When I worked at the Alliance factory, our FFR (field failure rate) was usually 3% or less. Folks, that's outstanding in any industry except maybe automotive. The initial N800 launch enjoyed even better rates. I have no knowledge of current rates (and couldn't share if I did) but they're nowhere near what one would gather from forum complaints.
