Lots of comments today WOWing before the majesty of Lion upgrade… Look, mah, no DVD! As long time Debian developer Bdale Garbeeput it “the idea that you should have to reinstall from scratch on a new OS revision is sort of an aberration in history, foisted on the world by shrink-wrapped software suppliers with motives other than technical…”

After all, isn’t Apple’s App Store an imitation of Debian’s APT repository or Fedora’s RPM package archives?Article first published as Upgrade In-Place was Availble Long Before Apple Lion on Technorati.
