For me, it would be whatever their position is on various computer-related legislation -- i.e. whether or not they are going to cosign the internet radio equality act, or what they think about net neutrality.

I think the specific machine sitting on their desk shouldn't really have anything to do with it.
(it doesn't affect the type of person they are, or in most cases, their positions, I should think.)

but one using open-source software or something else "off the beaten path" might get extra "worth mentioning" points.
