I've always used them. However, the iP5 screen seems to be highly scratch resistant with the "gorilla glass 2." I understand it can scratch, but I mean from just everyday use--pockets, sitting on table etc. Not needing one would be great. Zagg and wrapsol end up attracting filth, discoloring, and peeling at the edges. I went through at least 3-4 warranty replacements on iP4. Economically, buying protection accessories neutralizes the premium on reselling a mint device because you're still out $50-100 (or more) from purchases. In the long-run, I'm better off just taking a hit on the re-sale price. "Cosmetic" accessories are not to be confused with accessories that augment the functionality of the device--e.g., cases for operation in extreme environments or wallet type things that add convenience.
