When placing the image on your USB key, please use either liveusb-creator for Windows or livecd-iso-to-disk for Linux. We are also providing an appliance image for use with VirtualBox, as well as VMware, to allow even Mac users to test Sugar on a Stick. Later in the development cycle, SoaS will also feature specific images the XO.
Finally, please note also that we are going to have a test day on SoaS together with Fedora QA this Thursday (September 3). Let us know how it goes! In case you encounter any issues, please report them at our bug tracker: https://launchpad.net/soas
