Spigen SGP makes a few different film screen protectors for the new iPad. They're quite nice if you get them installed correctly, but not everybody seems capable of that. You have to make sure not to touch the adhesive with your finger tips (you're supposed to wet them with the spray provided).
In the near future (late April or May), Spigen will begin shipping its Glast screen protector, its premium tempered glass screen protector for the iPad (this screen protector is currently available for the iPhone 4/4S). I've been using an early sample of the Glast for iPad and it's promising (easy to install, no bubbles, very protective, and clear). Look for a full writeup on that one when it ships.
