I run Ubuntu on my laptop, desktop, and home media/fileserver, plus Debian stable on our main server. Before that I used Red Hat, and, well, before that Slackware back in the days when Slackware was all that was around.

I love apt, which keeps me on Debian-based distributions. And Ubuntu generally has better hardware support and/or documented workaround, which is why I switched my initially laptop and later desktop to it.
