Ubuntu in Windows, as a Windows Application

This has to be one of the coolest things I've ever seen: Linux running inside of Windows. This evidently fits on a USB thumb drive and can access Windows files directly. Apt-get even works! I'll be giving this a try once I have access to a Windows box again (Monday) at work.

The main thing that would hold me back would be typos on the (tiny) site for the application. I guess I'm making a pretty big assumption in believing that this will work just fine. How else can we find new software besides being trusting?

More info over at Lifehacker...I guess that can ease my mind if nothing else. I'll be waiting with baited breath for a Linux Mint version.
