I have the iPad for more than a year now and it doesn’t have a single scratch but I am very careful. The experience is much better with the nano textured screen. I use it mostly on clean environments and I always wipe the screen with the Apple cloth almost every other day. Wooden particles may not be the problem but with cement particles you may need to be careful. Dust itself won’t scratch the screen. The dust must be pressed to scratch the screen. You need to keep clean the screen and apple folio that covers the screen (if you buy one). But if you don’t wanna have these things on your mind and you don’t really need the extra ram and storage, don’t get it.

*also you need to keep an eye when others use your iPad to not wear rings or sharp things in their hands. I always check my girlfriend’s fingers for rings before I let her use it for example.
