You might also want to think about installing a backup program on your TX to back up the contents of the TX to your card. This can be very useful if you're away from the computer you sync to and your TX crashes. This way you have a backup with you at all times. Most of these programs will allow you to set a backup to occur at a preset time. Some will even allow you to set more than one backup set. I'm using Resco Backup and have found that it does a good job of backing up everything and restoring it without any hassles. A couple others are Backupman, & Backup Buddy.
