Absolutely. Every year I look to see whether it looks worth updating my phone. It took from the 3GS to the 6 for the first upgrade. I think the 6 will keep going for a few years yet. The only thing that I think the X could do that I'd like is an augmented reality version of 'on foot' turn by turn directions. Not really worth it for the enormous amount of money. Of course if they got rid of the appalling Lightning connector and went back to something that actually stayed connected, I'd buy such an iPhone like a shot!
