See now you say most are not, but so far judging by this thread it seems that it's only yourself and Graham that haven't experienced any issues so far.
So I'd say it's the opposite and most users are having problems.
Very few people without problems post.
I remember a customer service engineer commenting that he sees significant more problems on one model rather than another.
He of course never sees ones without a problem.
He also did not know that unit he saw most sold nearly twenty times the other model.
Edit: your problems do appear to be a little unique and changeable.
I am sure you have tried a factory reset and a power cycle - have you tried them one after the other? (Factory reset first).
