Folks, I think my point was this...no matter what you do to optimize the software, a bigger battery will always give you more run time. I realize this is a Maemo forum, but I'm looking for some thoughts on the hardware side. E.g. laptops have extended-life batteries, even HTC has one for their phones (http://talk.maemo.org/showthread.php...999#post492999), so why not for the N900?
