Every phone I own gets a BoxWave Anti-Glare ClearTouch protective shield. It slightly reduces the full grandeur of the display's vivedness (but not by much), but makes it finger print resistant, anti-glare and doesn't affect the responsiveness much at all. I rather have the screen protected and not showing prints.
Edit: I just got mine setup with the shield this morning, and I have to say that it is actually EASIER to use since my finger does not stick to the screen at all. It is actually a much better user experience, IMHO.

I installed the Boxwave clear protector last night, I have to say it is much better than Zagg which I have used on many devices including my Hero until last night. The Boxwave is much smoother to touch and the prints seem to be less as well. Thanks for the post!
