This is a rather interesting promotion. Think Secret has a decent rundown of what’s in the mystery boxes. These new units fix some really big issues with the mini (faster hard drive, more video ram in particular). That faster hard drive will make a big issue with performance on the mini. It’s a really cool system, I love it. My biggest complaint is 256MB’s of RAM it originally shipped with (now a better 512), and the 4200RPM hard drive.
