I've read a lot on here about the benefits of having and using an iPad, on many front - using it live for charts and setlists, using it to help with practice and playing along with songs, etc etc. I have an opportunity to pick one up at a good price. My question now is - which one? It looks like I can choose from an iPad Mini with Retina display, an iPad Mini without Retina, an iPad Air, or an iPad (I think this makes it a 4th Gen) with Retina. If I was choosing for personal use around home, reading and the like, I'd go for a Mini like my wife has. But, I wonder if the Mini is more difficult to look at when mounted on a stand and using at a gig. Have people found that the difference in screen size matters? I've also read (not here) that with the Retina display that the screen size doesn't matter that much anymore. Or, maybe its all about the processor speed and I should just buy the most current one. Any thoughts and experiences from those who have and use them would be much appreciated! Oh, if it matters - I'm 41 and reasonably adept with electronics, I do wear glasses but my eyes are still quite good, and I gig/practice recreationally between 2-4 times a month. Thanks in advance! P.S. I hope this is the right forum for these questions - if not, my apologies and mods go ahead and move it.
