I have never had to pull the battery and I don't reboot my phone. I have been really happy with the n900 since I got it. The browser slows down every so often but usually when viewing content heavy sites. I force quit the browser a few times a month when it becomes unresponsive. Email would be the one thing I would complain about. Thankfully there is a good community here and someone posted a fix that solved my problem. I don't really have any performance issues. I did overclock it for about a month but the battery took too much of a hit. I'm running it stock now and can easily make it through my work day and most of the night before I need to charge up the phone.
