Not likely to happen. Any person with at least a brain stem can use Ubuntu. It's VERY user friendly. Most everything in Ubutu just works.
I have not tried Ununtu yet. How does it compare to Debian? That is the one I have been setting up here. I also have Red Hat and Suse. Did not care for Red Hat, have not gotten around to loading Suse yet. Starting to get too comfy with Debian, I guess.
I started playing with linuxes on an old P3-733 clunker doorstop. Surprise, it was not a clunker any more. I do have a few annoyances with network print sharing, but am pecking away at them.
