There's been a lot of talk in the past of carrying a USB drive on a keychain to store important documents, med info, and stuff like that. Just came across this credit card sized usb drive that looked pretty interesting:
Walletex Wallet Flash
Anyone tried using one, as a back up but also day to day? I'd be curious about its durability in a wallet and repeated use every day.

It'd be awesome to replace a chunk on the keychain with a slim card in the wallet, even if it's accessed every day.
