Hi Guys, My first post in a long time. I might have a chance to upgrade from my iPad Retina (4), to an iPad Air (5) or even a generation 6, if I have the patience (My wife would be getting the iPad 4). Not sure it's worth it though. I was wondering if any of you have compared the performance of the two, with Lightroom Mobile, which I honestly don't use on my current iPad, due to somewhat sluggish performance. Thanks!
