wrt the mini/micro USB I've read a long time ago that they last for 1000-2000 inserts where the current "big connector" has many more (sorry no link)
Believe it or not the small connectors are designed to last MUCH longer then the big ones!
Standard connector: 1500 connections (only!)
Mini-USB: 5000
Micro-USB: 10000
