So I have been looking for a bigger and badder battery for my n800. Right now I just have the stock battery and a cheapo back up from ebay, but pulling out one battery and swapping in another on the train is not that convenient. The trains are pretty packed here so I barely have enough to scratch my butt much less swap batteries. Anyways, this is what I am looking at:

I was just wondering if anyone had any thoughts on this battery or if anyone knew of a different (and maybe larger) battery. Thanks.
