I've used various iPhones for the last few years as pocket-sized iPads, but never used the phone part. Other than the size and the phone (of course), what features do I LOOSE going from an iPhone to an iPad mini 4G? Do I loose anything? I know some apps are lost going from iPad to iPhone, but what about iPhone to iPad? I'm still somewhat new to the Apple software/apps thing, so to hear from the experts and familiar here would be so handy. Thanks in advance!
