Look at the threads that discuss the BSE Best Skins Ever skin and ShieldZone.
But to repeat since this thread might be the only one members look at:
1. The advantage of a full skin is that it will protect the entire phone, not just the display.
2. The Pearl is slippery. With a full skin, the slip-out-of-your-hand factor is eliminated [note I said "slip" not fall].
3. The full body skin eliminates seeing smudges and finger prints that accumulate on the Pearl's surfaces. Until I applied the BSE skin, I was wiping down my Pearl every few hours with Windex.
4. Applied correctly the BSE skin does not diminish the clarity of the display area. See below.
Bonus Tip: The Seidio rubberized case, which I prefer over similar lesser quality cases for sale on eBay for $12, fits better with the full body skin.
Sidenote: I do wish the Seidio rubberized case was $20 or less rather than the $30 it currently costs.
