I just bought a retina and I'm nervous about commuting with it. It'll be in my bag but I'm just worried I'll get robbed or something. I'm probably still in my honeymoon phase with it though. I take the subway to work and school. The mornings aren't bad but I get off work the same time many rowdy HS students do. I really hated HS haha. Anyone else like this during a new purchase? I even still exercise caution with my iPhone by not always pulling it out when commuting. Safe or paranoid?
