Improved camera is always enticing, especially if rumors of triple lens (UWA I'm hoping) are true but I'm shooting more with a camera again so not really a need, if they up the MP or larger sensor I would definitely get one.
I'm finding the X with IOS 12 feels sluggish but still works for my need so not in a rush to upgrade.
I'm considering the newer Ipad Mini more though so that I can work remotely without having to carry my 14" laptop with me.
Have an Ipad Air 2 but it's slow and bigger.
