This morning I got up early and replaced my Ubuntu 10.10 installation with a nice shiny install of Linux Mint Debian Edition (LMDE). LMDE is based on Debian testing, and is a rolling release. I've always wanted to try a rolling release, and one based on Debian ticks all the boxes. The important thing is that Debian and Ubuntu share the APT packaging system which thinking about it, is probably the main reason I use Ubuntu.
I've used regular Linux Mint a few times in the past and I've always been impressed, although I always end up back on Ubuntu, I'm not really sure why that is, probably that I can't wait to test out the newest stuff so I jump on Ubuntu as soon as a new release comes out. A rolling release of course solves that problem.
