I got a matte one but it severely diminishes the resolution of the screen. A tried a glossy one also that came with the case which preserves the res better, but leaves lots of fingerprints :S
Waiting for the Zagg HD screen to reach my door, ordered the front and back combo. Hopefully it won't mess with the beauty of my screen too much.
I have Ghost Armor for screen and the back of the iPad. I actually had it installed in the Mall from the GA guys themselves. So, it's pretty much flawless
My screen goes nude. But I will get a skin for the back. That aluminum will scratch very easily....before you know what's going on. That's why I keep it in a folio case, but if you ever take it out if you are not extremely careful you get a little scratch...then when you sell it you have to claim the condition is good (which, is probably all you can claim anyway but I still like it to be as close to perfect as I can possibly get it). I just like my used stuff to be like new when I sell it. I feel better about the sale under those conditions.
Bought the ZAGG with the ipad. Doesn't appear to hinder the resolution - remains to be seen how it works out.
I have a two year old screen protector on my iPad 1 which is still pristine to this day. Knowing this, I am NOT putting one on my New iPad.
Go naked or stay home. Screen protectors are unnecessary on the iPad series of tablets. They detract from the beauty of the display and offer no real protection.
