Maybe you want to give Linux a try on your netbook with Ubuntu's Netbook Remix, but don't want to have to wipe your system to do so. Luckily, you can install and remove Ubuntu from Windows, just like any other application.
At the How-To Geek's abode away from Lifehacker, writer Matthew details the pretty simple process of installing Ubuntu as a kind of sub-system in Windows using Wubi. Pick "Ubuntu Netbook" from the Desktop Environment menu when installing, and you're on your way. Matthew also details how to make your Windows files and folders easily accessible from your new Ubuntu desktop, along with explaining more advanced Windows/Ubuntu boot options and providing a basic tour of the small-screen-focused Ubuntu. It's a pain-free way of trying out Ubuntu on a netbook and seeing if it works for you.
Got a netbook that Ubuntu Netbook Remix just absolutely sings on? Have a few things you wish were fixed in UNR? We'll gladly take both talking points in the comments.
