Should i buy a screen protector for the DS?

Krushaerm, I wouldn't advise using "Glass cleaner" as in like... windex or something.
I mean't the cleaning cloths used for things like glassesI can't see how anyone manages to scratch their screen :S no-one I know with a DS (and thats upwards of about 20 people) has managed to scratch their screens and none of us have screen protectors (one did but only because removing it actually lifted the screen itself with it, we ended up wearing out the adhesive over a week or so with a slightly moistened cloth)

It may be a factory defect with my stylus (Although its happened to two different units) or it may be the dust in the atmosphere or something (I live in the southwest US where its more dry and dusty) or maybe I'm just heavy handed or I play my DS more than some do. *shrug* Whatever the reason, it happens with me.*lol* Thx for clearing up about the glass cleaner. It definately didn't sound like a good idea mixing ammonia and plastic.
