My Backup Pro is very good just know that it backs up to the Transformer storage and not to the micro SD Card. So you have to remember to copy it to the micro before you do a factory reset. It does really good for calendar and contacts but for todos and notes and stuff like that I usually use the individual app's backup and restore function. I myself am so used to iTunes and the restore from backup was flawless. It is really taking a while to get used to the Android change.
