I use FaceTime a lot and have been doing research on finding a case that has multiple secure angles. I have had a few cases but they are never secure in the stand and always slide out of the angle. When I use a case like the apple one it barely stays standing and almost anything can easily tip it over.
I did find a case that looks pretty awesome but wanted to see if anyone here has tried it, its called iPad Case Prodigy and it uses magnets for the kickstand. It does sound like a great idea.
