I haven't read this whole thread, but wanted to chip in my experiences with my new N900 regarding battery. In a nutshell, I am disappointed. It's worse than my previous Nokia N95. I have it full charged when I leave work. Then a 1:30 hour commute, using it a fair bit [what I bought it for] see's the battery down to about 25% charge if that. I am finding I need to charge it 3 times a day just so it doesn't quit on me. Maybe it will lesson when the excitement/novelty wears off. But I did buy it to use it for everything I am using it. Does anyone know about a bigger, heavy duty battery for this? Thanks
