In my experience, pretty positive. I see Macs around campus frequently. In my team, people mostly use Windows, so there's definitely no alienation there. However, when people notice I mostly use Linux, I usually receive a chuckle for not using Windows--either out of irony or since we are highly encouraged to dogfood everything here. But that's usually the last I hear of it, so I don't think anyone sees anything wrong with it.
