Mint is a lot like Ultimate Edition. When I install Mint, I can play DVDs, MP3s
and Youtube videos -- immediately, without having to download anything.

Other than that, it is Ubuntu. It uses the Ubuntu repositories, etc. There is
one Mint repository, but I don't know what is different in it.

The only odd thing is that Mint comes with no games.

There are also few visual differences, just a bottom menu bar, different
notification of updates, a slightly different presentation of the programs you
can run.
