I think most people don't have the need to push their iPad particularly hard and so hardware as old as the iPad 2 is probably good enough. Myself, I upgraded from 'The New Ipad' (whatever number that one was) to the latest iPad Air 2 for the massive performance boost. I'm a software developer and use my iPad for the Omni tools (OmniPlan, OmniFocus, OmniGraffle) and also for Keynote. My older iPad was having trouble switching apps because of its limited RAM. BTW, if you're thinking about getting the Omni tools be prepared to spend some money. They work best when you have them on all three devices - laptop/desktop, iPad, and iPhone. Each has a different UI devoted to that platform and somewhat different functionality. Sometimes when I fly I don't even break out my laptop. I instead do planning on my iPad using my logitech bluetooth keyboard.
