I like the protection, but I also don't like the bulk. But if protection is what your going for, that looks like a great case he's got!
Ever since the Optimus V, I have grown to like just a basic silicone skin. When I had the Blackberry Curve with Virgin Mobile in 2010, I had an Otterbox. I did like the protection as well as the grip but it was a pain to put in your pocket haha!
The great thing about this phone is there is an endless supply of cases (and even extended batteries that comes with cases to fit). A quick search on eBay or Amazon of "Epic Touch 4G case" comes up with lots of nice choices which is a very nice benefit in owning a well known branded device like ours
