I'm with you MrPlow. It is why I like the skins - some protection from scratching/bumping - but minimal size increase. I've tried several bumper type cases for the iPhone - but it ends up feeling huge compared to just skins.

I picked up the Jot Adonit - but I was worried about scratching.

I picked up a 6 pack of screen protectors.

I put the Antiglare on But I don't care for it. It does reduce glare, and works pretty well in direct sunlight. All other glare is pretty reduced. I'm going to stick with it for a while - before I try out the diamond and -anti-fingerprint.

The Jot works great with Penultimate, and Notetaker HD. Didn't work so well with Notes Plus. UPad is currently broken with the New iPad (iPad 3).
