Those numbers hardly keep their ground in practice.

Sure - idea of putting D+,D-,+5V and ground springs to male plug, and leaving solid pads on female side is OK, and I'm all with it. port's case springs ("tooths) are irrelevant, though - in "big" USB, they were present on female ports cases, and I yet have to see single spring of this type broken (unless someone bend it on purpose).

The problem is - as I've stated in previous post - way used to mount microUSB ports to PCB. I'm 99% sure, that, while testing connecting cycles, they've checked sole port and plug, not port soldered to PCB via surface-only, like it's done in 99% of microUSB electronic. Basically, nothing to add, above what was written in my last post - this part of design just sucks, and we know it "personally".

Maybe there was some good will, due due to this single flaw, every serviceman I've ever meet, claimed to have *awesome* number of broken microUSB port repairs, if compared to miniUSB and normal USB era. I don't argue, that microUSB port/plug design isn't superior, but way of mounting it to PCB is horrible and wrong from foundation.
