I decided not to go for screen protectors. But there I go again living dangerously I felt it would be in the same league as buying a new sofa and covering it with plastic. My N900 is about six weeks old and so far so good! I'm meticulous about keeping the screen clean though, and I think this makes a big difference. Plus I try to mainly use the stylus... I figure I'll have it serviced if the screen ever gets bad enough. The replacement cost, however, will likely be equivalent to a new device :/
