Again, where's the usability? The only things you pointed to the last time were the results
of Red Hat hackers' work on Java and then some dodgy Flash stuff and media codecs. The latter
are just as available in Fedora or Gentoo or whatever as they are in Ubuntu for those that
want that stuff.
I've used Ubuntu fairly recently (not out of choice) and am not blown away by any usability
differences between it and any of the other current major distros. I again invite you to point
to some metric so that this is not merely a yes-it-is-no-it-isnt exchange. Otherwise you may
as well merely shorten your post to "I have no problem with proprietary software and patented
codecs and I like the Ubuntu wallpaper."
