"When most people talk about Ubuntu, they usually mean our
flagship product, Ubuntu Desktop Edition. Sometimes, they might
mean the Ubuntu project, or the community of people who work on it,
or various other things.
"Similarly, Debian might mean the Debian operating system, or
the package repositories, or the project, and so on.
"This gets a little confusing sometimes. When I'm talking about
Ubuntu, I've started to use more specific terminology to explain
what I mean, and this seems to help people understand better the
nature of the whole Ubuntu. In particular, I use the three Ps:
* a portfolio of products, including Desktop Edition, Server
Edition, Netbook Edition, Kubuntu and more. These are software
bundles which can be downloaded, pre-installed on retail computers,
and so on. Each one is designed to meet a certain set of user
needs, and to work on a specific form factor of computer."
