This screen protector infatuation is a matter of personal opinion.

If you are the type of person who leaves the plastic on a lampshade in your home after you buy the lampshade, then I suppose you'd leave plastic covering your car seats, your living room furniture and your personal electronic gear.

My Brother has screen protectors on everything. When I try to use his Dell Pocket PC I have to look at a screen thru his scratched up plastic screen protector. LAME. Come to think of it he put seat covers on his brand new car seats.....why? to keep the seats nice for the NEXT OWNER? The heck with that. If it were my car, I WANT to enjoy the seats / wear them out.... the next guy is buying the car used AFTER I enjoyed it. I am not going to sit on plastic preserving the seats for someone who didn't buy the car new. I don't want to suffer looking at my N800 screen thru some "sheet" preserving the N800 for the next owner. I want to fully enjoy it, and that means the next guy gets it used, whatever that entails.

I want to see the beauty that is the 800x480 LCD screen with nothing between my eyes and the crisp LCD. A slab of plastic covering the screen is hideous. But that is my opinion.

I have been using my new N800 heavily for three weeks with nothing between me and the LCD. I poke at the screen with my fingers, fingernails and the Nokia Stylus. The screen is fine. Zero scratches. I have also owned Pocket PCs for years (first was the Cassiopeia E series, then Dell X3, X5, X30 Advance) and NEVER used plastic sheets over the touchscreens. No scratches. One key is to not let dirt accumulate on the screen. The dirt rubbed with the stylus will cause scratches. I keep my screens free of dirt and refuse to use those plastic sheets. You do what you want. I dislike sheets of plastic over my LCD screens.

That's my feelings on the matter.
