I live linux usb is a great way to try out a new distro to see if you like it or even if it will work on your machine. It is quick and simple. UNetbootin is a cross platform program that guides you through the process of creating a live usb drive.
YUMI is another way of running live usb distros. It is geared to allowing you to install multiple distros on one stick and makes it very easy to add and delete the ISOs.
I will write more here later, but for the time being, download the software and give it a try.
