The motorolas I have had always have one problem.  The charging portal doesn't charge always.  For instance, I plug it in, and then get charging errors "unable to charge."  At first I suspected the charger to be at fault, only to realize that it happened with three different chargers, on both my phones.  No such problems with any of my nokias, even though I prefered motorola due to the sleek designs motorola carries, and the affordability.
