"All in all, there’s not one key area where Fedora has improved, but it
has a lot of evolutionary improvements in various domains. With the
ongoing migrations to Btrfs and systemd, Fedora 16 lays the groundwork
for an exciting future. If you want to experiment with the newest Linux
technology, as always, Fedora is the place to be."
