The day she pulled her little routine on one of the vice presidents was her last day at the office. She was out of the building before lunch.
As developers, we like to pretend that we're above office politics, or that our tools are our own, and other things like that. Nope. To managers, we're all as interchangable as furniture. And it wouldn't surprise me that much of the offshoring is due to the combination of 2 facts: that they have the power and we don't; and that the jocks are pissed off at the nerds because we don't kiss their asses enough. Just look at the title of one of the latest fad articles and books to come out of the Harvard Business Journal: does I.T. matter?. Remember what PG says about mental fads? "What scares me is that there are moral fashions too. They're just as arbitrary, and just as invisible to most people. But they're much more dangerous. Fashion is mistaken for good design; moral fashion is mistaken for good."

But I think its always over-the-line when a touch can actual do some small amount of damage to the item - any touch to laptop screen is going to be reducing its lifetime at least a bit.
But can anyone here honestly say that they've ever had to get rid of a laptop even one day earlier than they would have anyways because of the damaging effects of finger oils on the screen? There are so many things in a laptop that degrade more quickly than the screen surface, I just don't think it's a very legitimate worry.
What's the worst case scenario from touching a laptop screen a lot, other than the minor annoyance of having to wipe the crap off from time to time?
I think it is so much more polite to just ask people not to do it again. Just asking them will get the point across and will not make them feel awkward.
