So I bought a 4GB IronKey a couple of weeks ago. I really love this device.

Like most of us, I have dozens of accounts on-line, each with a unique ID/Password combination. Many of these accounts I access only rarely. Since I never write down passwords anywhere, and don't duplicate passwords, I often find myself in a lengthy password recovery process each time I need to access the account.

I now have access to all my password protected accounts from a device that lives in my pocket.

The IK comes with a password manager and a portable version of FireFox to allow portable sessions to be created from any system with a USB connection. Remove the IK and you remove your presence from that machine.

Access to the IK is via a single user-settable password. Data on the IK is protected by AES 256 encryption (Son of DES). Enter the password incorrectly 10 times and the data on the drive is physically, albeit silently, destroyed.

I know there are freeware programs like KeePass that can be loaded on conventional thumb drives, but they don't satisfy my sense of paranoia like the IK does.

It's not perfect, by any means, and I don't have 4GB of data that I need to protect, but it really suits my needs.
