Maintained, a bit slow on the updating sometimes, as I mentioned. But a big factor for going with Ubuntu was if you're looking at software out in the wild, chances are they'll have either an Ubuntu version or something that will work with it. I'm not a fan of compiling stuff (although maybe with more Linux exposure that will change too).

In hindsight that's probably not a great reason, after all it's why Microsoft dominated the field for so long.
