I'm looking for a ipad air case. My son uses it so I bought a Griffin Technology - Survivor Case but it is so bulky and a pain to remove. I'm trying to find one that protects it similar but not as bulky, something that protects that back and sides. Maybe get a screen protector? The survivor case has this thick plastic cover over the screen so sometimes it hard to use the touch screen. Any recommendations? I saw some on Amazon for like $9-$20 but who knows the quality.
