I’m embarrassed to actually use the iPad for anything. I’m leaving it under my seat because I don’t want to attract any attention. This reminds me a lot of when I bought my iPhone. When the iPhone first came out they were so rare and exotic for the six months or so that every time I’d pull it out people would be like, ‘Woah! Is that an iPhone?!’ And so using my iPhone in public felt like bragging.
