My advice is: don't use the N900 when you want to save on batteries.

This is not as stupid as it sounds. I don't know about you, but most of the time I am surrounded by hardware that does a better job than any cellphone or internet tablet for music, surfing, communication, games, programming and whatever. So I only use the N900 for phone calls and when there is no better hardware around.

A special case is the routeplanner, butt hen I connect the N900 to the cigarette lighter.

Hope this helps you get a more realistic view on hardware and the use of.
