Fedora media writer is fantastic. You're right, it can either automatically download a fedora iso, or you can just feed it any image. Its so simple and handy for me, to the point a recent foray back to Debian was cut short because there was no included equivalent and the alternatives were just a hassle.

Although, the `cat liveimage.iso > /dev/sdX` tip mentioned in this thread is very handy and is probably enough for me. Anything I can do without a distro specific tool is a win.
