just out of curiousity... what kinda of information would NOT be recoverable??
I dont mean to sound snotty or snide, i just can not think of ONE instance other than intellectual property that does not exist in someone else's database (usually the provider or IT dept. of a business)
You're right in saying that the vast majority of data that you'd store in a program like eWallet or !Password would be available somewhere. But reconstructing and re-entering that data could take a very long time. In my case, I have many items that require more than submission of an e-mail address to recover. And even if I had my data in written form, entering it all (including URLS, user names, passwords, and so on) on the iPhone would be maddening.
I realize that eWallet and other apps that don't have desktop versions back up their data when you sync the iPhone through iTunes, but I also like the convenience of entering data on the desktop. But that's just me....
