I keep mine in the desk in case I have that unfortunate loss/theft experience. Why lose everything at the same time?Good insurance policy Many people depend on the hotsync feature with their PC to save their data in case of a loss of battery or the old "Fatal Exception" error. Re-syncing with your PC only brings back your data ( phone numbers,appointments,etc) not all the programs you have loaded on the Visor. You probably didn't save the original file you downloaded, so know you have to go find them on the web again. This module saves everything so you don't have to worry. It's saved me lots of time.
