I have a MacBook air and an iPhone 6 plus. I'm perfectly happy doing things on my iPhone like web browsing. However, everyone on these forums talks about their iPads as if they were a nessacary and integral part of their computing set up. I'm an iOS developer so I do have an iPad, but I just feel like it has no use for me. What do you use you iPad for that you can't/wont do on an iPhone pr laptop?
