I have an early-2009 iMac, a mid-2011 MacBook Air, and an iPhone 4S. As a tech fan and a lover of Apple products, I've always been fascinated by the iPad and follow the launches of new products. Yet, I can't figure out how I'd actually use an iPad, so I've never bought one. I feel like I've got my bases covered: music/photos/movies (iMac), travel/school/work (MacBook), games/text/communication (iPhone). What am I missing? How do you use your iPads? What function do they serve for you? Sell me.
