i always recommend a screen protector, but that is me. i am very clumsy....almost butterfinger clumsy. a screen protector is a must.
i think the top two for me is zagg shield and whitestone protectors. i like zaag, because there is a zaag booth in a nearby mall that i can just go and they will install the shiled for me. whitestone you will have to do it yourself, but it looks like they have this cool contraption that makes it easier to install.
for me i'm just lazy.....LOL
