I have a iPhone 4S and a Macbook Pro. I'm buying my first iPad with the iPad 3 but before now, I was always unsure if I ever really needed an iPad. Off the top of my head, I imagine web browsing would be more enjoyable on the bigger screen and that iPhone apps that are also on the iPad would be more engaging with more content on the screen at once. Other than those two obvious reasons, why do you own an iPad and why do you continue to update every year? What are the main features that you depend on with your iPad... features that you would surely miss if you could no longer own one? Or maybe you sold your iPad 2 a while ago and are really missing some things about it... what things?
