I used by purchase protective screens for my mobiles and they were always very difficult to fit properly but these newer 'glass' screens on the iPad and iPhone don't really need them although I never put keys etc in the same pocket as my iPhone. My old Samsung was badly scratched before I fitted a protective film on subsequent models but I have both an iPad and iPhone now and although they pick up finger marks it is almost impossible to scratch them in normal use. To be completely safe the magnetic folding cover available for the iPad at £35 is brilliant and will also double as a stand for easy viewing.
