iCloud is the other featured cloud provider that AgileBits proclaims on their website, although I wouldn't recommend it. Not a knock against Apple, but I prefer to diversify my technology and not get locked-in into any one service.

I just switched back to 1Password from LastPass, and I'm just syncing between my iPhone and my MacBook (my only computer ATM) using wi-fi sync, and backing up my 1Password data on my MacBook to tarsnap.

I've seen someone else say they sync their 1Password data using BitTorrent. Haven't tried it myself, but that seems interesting.
