Hi, everyone! I'm hoping to some get some advice. I've been working with an IPad 4 since I upgraded from the original iPad. I love my iPad and use it everyday. My reading library is is on it (and I read a lot.). Occasionally, via my Tivo, my TV shows are on there. That's in addition to basic news apps, email and so on. I teach a few courses online; I mainly use a laptop for this, but the Ipad is handy to pick up and check a few things every now and then. Even though I've owned several iDevice and computers, the only time I've had problems with the iPad was a cracked screen during my last move. It's been replaced twice and is thinly cracked again due to the repair guys not explaining until now that when the screen is replaced, it is much more delicate than ever before. (I keep my device in a good case 24/7, so the replacement materials must be fragile.) All of that is history--Given the amount of usage (high) and the fact I can't get any trade in money, do you think the IPad Air 2 is worth it for me? Other than a fresh screen, will I notice that much difference? Any advice and thoughts would be greatly appreciated. Please and thank you!
