Thanks Terrence, as I'm seriously thinking of buying one of these your blog has gone to my number 1 most helpful website ever! I should have asked this question at the time but I forgot. I've read the battery is soldered in. Is this true and if so what on Earth do you do when, as all rechargeable's do after time, you find the battery holding less and less of a charge. Is there a way to change it at all?
