Relatively new to BB. Former Palm Treo user and I miss the ability to backup my BB to the local SD card. While it was probably critical on the Palm, I used it for many non critical things. Backup, install new app, restore backup to revert to preinstalled state. Since I found it necessary to wipe my Palm device regularly to correct a spontaneous reboot condition, I would have a saved backup of a fresh install of all my most essential applications. If I had problems when I didn't have time to figure it out I could do a backup then do a restore of my essential install. Back in business in a few minutes wherever I was.

I have wiped my BB once in the last 6 months so it isn't a common thing. I have rarely needed to reboot but there are times when I would like to try a different combination of applications to see about performance differences.
