So in the end I just decided to keep both models as I ended up getting both at less than the price of just the X alone. Basically I've got $400 in both new unlocked devices so I'll just swap back and forth. By far I like the XA smaller subtle size and no side bezels. On paper the size difference seems to be nothing but in hand, the XA is hugely the better and easier one hander device although it's slower. Being new to Sony I'll just keep both and enjoy each model for what I need or mood I'm in. All that struggle to decide on which one and ironically I end up with both. Mainly or only due to the stellar deal I received. I have a feeling though that the XA will end up being my choice and the X will come into play down the road once the XA plays out.
