It would be nice to have an application for N900 that would count the charching cycles and inform the battery state and even guide through the recalibration. I have never really figured out how the battery thing goes (no need to try to explain) but if it is unavoidable the app would like warn with text and sound "after three charges you need to recalibrate the battery" and then after those "let me guide you through recalibration", "charge fully", "full. Remove charger", and then when battery is empty enough "1 minute untill your device will reboot.", and after reboot "Congratulations! Battery recalibrated!".

Maybe something was said in a wrong way but you got the point. Would it be difficult to make an app like that?
