Yeah, it feels like it's perfect as a phone. I absolutely love it. I'm actually quite surprised that they take what I think as a perfect product and still add stuff to it. Very impressed by Apple in every way. Great product. Great engineering.
Somehow they always dodge the reverse Osborne effect, haha!
Honestly if it weren't for the USB-C I'd probably just keep on keeping on; but this might be the time to jump from the Xs.
