flyweights! sounds like you 3-day battery people are hardly using the device. I regularly run the battery dry in under 3 hours. But I'm actually USING it for those 3 hrs. Browsing, watching video podcasts, gaming, downloading files over wifi, listening to music. The N900 is a computer to me, not some device to just glance at instant messages or call my mom on every now and then with. Hardcore baby, burn that battery up!
