Those screen protectors are cheap(?) insurance. I use a Zagg Invisible Shield (front only).
You do have to be really careful and take your time putting it on to prevent bubbles, but once there, I think it works great! (Disclaimer: I do not work for Zagg and they did not pay me to say that!)
The best part is the guarantee:
"If your invisibleSHIELD ever becomes scratched, torn, or damaged while protecting your device, we offer you a free invisibleSHIELD replacement for as long as you own your device."
+1 I use IS on all my devices. I bought the one for the iPad and it's easy to install and it works great!
