If you're a Linux fan, you're probably familiar with Ubuntu. This free operating system will run on almost any system. The next release of Ubuntu is 10.10 and it will be supporting multitouch gestures. That's great if you have a multitouch screen or a touch/track pad like Apple's Magic Trackpad.
Do you have an older PC that's just sitting around? Try installing Ubuntu and experience the world of Linux. You might actually like it.
