FUN FACT: In 1975 Western Digital was the largest independent calculator chip maker in the world.

WHY COMPLEX IS CO-SIGNING IT: You need an external hard drive. And if you have a Mac, you need this external hard drive. Made exclusively for Apple computers, Western Digital's Firewire 800 powered My Passport Studio let's you carry around 500 GBs in a device that can fit in the palm of your hand. Even cooler, it has a screen on the front that you can personalize to tell you exactly what's stored on the drive. It also shows you how much free space you have on the drive even when it's not plugged in. That's hugely important if you use you an external hard drive as much as we use ours. The fact that they are designed to fall in line with most of Apple's products is a plus, too. You can head on over to Western Digital's site to cop, but Amazon has it $40 cheaper. $140 for a 500 GB HD that can fit in your pocket? You can't beat that.
