I purchased the
Moshi iVisor AG Anti Glare screen protector because I bought the IPP primarily for drawing and haven't been enjoying drawing on glass. Now, I couldn't be happier. I had the Moshi installed in under a minute and later removed it and re-installed it to remove a piece of dust I could feel but not see. For me, the matte texture makes a much better surface for drawing with the Pencil than the iPad glass. I also love that it is anti-glare and anti-fingerprint, and if there is any reduction in clarity, I don't notice it. I'm actually a little amazed at how smooth and clean the screen looks.
Prior to the Moshi, I had the
Tech Armor ballistic glass and that is a great screen protector if you're looking for a clean, clear, glass protector that is barely noticeable. The only trouble with the Tech Armor for me at all was that it was so much like the IPP glass I didn't enjoy drawing on it.
So, after owning two screen protectors here's my two cents: If you want to use the IPP for drawing or writing and are looking for a screen protector that is anti-glare and resistant to fingerprints, the Moshi is worth the $35. If you are looking for a screen protector that very closely resembles the iPad screen, you can't go wrong with the Tech Armor ballistic glass at $15.
