I just bought my second Mac Mini (2012 model) last week. My previous Mini was a 2009 model which had the rubber bottom. Now I see that the current form factor has a solid plastic bottom which is quite slippery. I am sure there are stories of Mac Mini's flying off of desks. I'm just curious what everyone does with their Mini's to prevent them from sliding around. Do you apply a rubber adhesive to the bottom or just leave it as is?
