Want to try out Ubuntu Linux without giving up your Windows desktop? How about running Ubuntu from a USB drive on any Windows PC while still operating within Windows? Portable Ubuntu provides both of these computing options, no setup hassles or programming skills required. You do not even have to reboot the computer or set up a dual boot environment -- and no, you do not need to install any virtual machine software to make it work. Argentinean programmer Claudio Cesar Sanchez Tejeda released Portable Ubuntu in mid-April.
