M2Sysmon is a rudimentary system information monitor for Pocket PC 2002 devices, it was mainly built as a test project for me to test out both my Today plugin developement methods and also my Today plugin installer template.
You can download it from here
The battery uptime is very rudimentary... it just ticks. ;) To reset it tap on the plugin area and select reset timer. Another feature of the monitor is to show a summary of storage space availability, tap on the plugin area and select "Storage Info" a notification bubble with the space remaining of all your available disks will appear.
Lots more coming....
