I don't want the encrypted file containing ~all of my passwords in an unencrypted Dropbox folder somewhere. If I control access to my keyfile, I'm at least protected somewhat against brute force, weaknesses in the software, someone stealing my master passphrase casually, etc.

They also have a USB synching tool if you're not comfortable with Dropbox (I'm not).

I still use their wifi sync, but it never worked very well.

The problem I have (which isn't THAT MUCH of an outlier) is that I have an MBA, a MBP17-desktop, an iPad, and an iPhone. I want to be able to use all of my normal/boring/personal/medium-sec passwords from all of my devices, want to be able to add new services from any of those devices, and I want to be able to do password updates from any of those devices. Ideally without ever connecting cables -- my iPhone/iPad get plugged into a charger in the car or by the bed, but not connected to either of the Macs.

All of their sync seems to be built around one Mac, one or two iOS devices; the USB, the older wifi, etc. Dropbox is the only solution they offer which is many-to-many.

I'm also essentially terrified of corruption or losing the data file, so any but the most cautious and transparent sync scares me.

You can enable automatic backups to ~/Library/Application Support/1Password/Backups in Settings -> Backup on your Mac. It will then backup locally as well as do Dropbox syncing.

I keep a recently updated (every few weeks or after I enter something especially important) copy on a flash drive. Worse comes to worse and something gets corrupted I can always use that version.
