I can’t say for certain, but this could very well be the world’s smallest Mac. The OQO Model 02 UMPC has been hacked to run Mac OS X Leopard, breaking new ground for folks who might fancy themselves a pocketable Hackintosh.

Yes, I realize that some people may say that the iPhone is the smallest Mac, but the iPhone is not running a full build of Apple’s desktop/laptop operating system. By contrast, this OQO Model 02 UMPC is running the exact same Mac OS X Leopard that you’d find on an iMac or MacBook Pro. Sweet. The bootup time has been clocked at about 2 minutes and 30 seconds.

In case you get a little too much love for Cupertino in the process, the hackers have ensured that the OQO stays as a dual-boot device, happily running Windows Vista too if that’s what you prefer. And yes, everything from Wi-Fi to sound, power management to Bluetooth works in the OS X environment.
