I had something weird happen when F23 was the latest release.
Somehow,
probably through user error, I deleted my partition table and bricked my
only USB stick. I think I corrupted the USB stick firmware somehow. I have
only one computer so using another to get another copy wasn't an option. I
did have a back up Fedora DVD because an earlier experience in life when I
found myself without an OS and a broken installation.
I think that having a read only media option with physical damage as
the only
failure mode is valuable. I continue to keep a Fedora DVD even though I
prefer installing through USB.
If you keep Workstation Live or Server netinst, you should be still covered under the
current proposal. That doesn't mean other media won't work as spinning discs, just
won't be guaranteed to work.
