What worries me as well is the fact that he says the screen is very sensitive to scratches... Jerz: "The only thing that worries me when it comes to N900 display is its resistence to scratches and other damages. And it seems to be quite poor. I got the device without any protective case and the display got some awful scratches in just one day, and that's only because some sand grains got into the pocket I kept it in. So a good screen protector or soft carrying case seem to be a must. OK, now..." What brand screen protectors work well while not affecting screen clarity and sensitivity? I am complete newby in this...
