One thing that drives me nuts about mobile computing is when I don’t notice my battery is running low until my computer is forcing itself into hibernation.  Sometimes having a little battery icon next to the system clock isn’t enough, for those times BattCursor is a lifesaver.

BattCursor uses Windows Aero Glass (the component built into windows that makes the boarder around applications in Vista/7 transparent) and your cursor as a visual reference for your battery life.  You can set the colors for full charge, half charge and low battery, use your mouse as a visual guide to battery life and even have BattCursor control your power profiles and change your CPU or backlight brightness depending on battery status.
