Yes! that's my prob too. Battery life period is too short without a serious warning.

I am 42y & my interests are different, but I've been satisfied to mess around with its applications.
Look, at least, there's a nice forum here to share experiences. Even some others have forum but not useful like this.

regarding age and interest I confess that N900 was my best friend during last 4 years and still I am using it but not as a phone!!?!

Now, I use Nokia C5-00: less and limited applications but I can carry it and the battery answers my need.
