At present I'm using my MP constantly but it's not always doing work stuff... and have recently I've notice the electricity bill to be astronomically high! Kinda like having a one or two bar heater on twenty-four-seven. Know what I mean? And, for a little while I've been using a MBP for the same task but I find condition the battery every so often to be a right pain in the rear, especially since it's not my main laptop and it's cells are constantly pumped full most of the time, thus constantly connected to the wall outlet So Yeah! To help cut down on my super high fuel bills and make my life a little easier. I'm thinking about buying a Mac Mini of my own, it'll probably be completely headless, cause I'm thinking of using it purely for downloads and huge online file transfers etc. I am however curious, does anyone else use theirs as a slave, for the same or similar tasks?
