Seamless Ubuntu inside Windows
Just saw this rather interesting development of the Ubuntu platform. It allows you to run a full Ubuntu enviromnent seamlessly in Windows. It shows apps individually in the Windows taskbar, can access local hard drive resources and is both persistant and portable allowing you to run any ubuntu app from inside windows just like a Windows app.

Could be really useful for development and testing if your on a Windows machine and preffer seamless access to your resources.
