I have tried a couple of methods, inclding getting a hold of the dell brand, and using transparency etc. and what I've decided is this:
1) it causese problems when it gets dusty as it traps dust inbetween them usually
2) the tab that goes under the sides of the screen, if there's the slightest amount of dust in there, ameks touching the frame touch the screen.
3) I realized I didn't actually care that much about scratches
4) I hve no intentions of reselling
after 3 and 4 I realzied that If I keep the screen and stylus clean, I won't get that many scratches anyway, and cleaning was a task I had to do with or without protectors, so I go with none of the above.
Honestly, a few microscopic scracthes yo have to turn the screen off, and strain your eyes to see isn't that big of a concern for everyday use...
