Re: Are there testing/experimental versions of Ubuntu?
Ubuntu does not have those series like debian does - that would mean that Ubuntu is a rolling release, but we do have a beta version of the upcomming version of ubuntu (which will eventually have to be upgraded)
They are avaliable here http://cdimage.ubuntu.com/daily-live/current/
Note that they are _extremely_ experimental, and can lead to broken systems that will require a reinstall at times.
Don't waste your energy trying to change opinions ... Do your thing, and don't care if they like it.
