I'm extremely excited to own a 1Password shirt. I got it today from the good folks at AgileBits, and am super pumped to answer all the "what does your shirt mean?" questions.
If you've never heard of 1Password, do yourself a favor and check it out. It's a application to basically create super-secure passwords for your digital life, store online payment info, and basically just organize all the information you need to keep secure. It's a life-changer, Mac-wise. If you have heard of 1Password, grab one of these shirts for yourself.
Either way, you need to have one of these shirts. The 1Password goodness must be shared!
