When you're trying to compete in the phone-making game, there are certain challenges. On the one hand, you want to dazzle customers with innovative features. On the other hand, you want to keep the suit-wearing shareholders happy with growth and strong, continued sales. The bottleneck in this equation is often technology. You can't force it to progress. So once you've more or less caught up, you're left with a choice: Innovate with software/hardware design, or take a risk with gimmicky features. Any of the above will do in lieu of the (unspeakable) alternative -- not releasing a new model this year.

We're not trying to preload this review of Sony's new Z3 flagship, which arrives barely six months after its predecessor. Or maybe we are. What we're definitely doing is spelling it out right here in the intro: The Z3 looks a lot like the Z2, and after a quick glance at the spec sheet, you might argue it sounds a lot like it too. This is pertinent because, by its own admission, Sony isn't doing very well at competing in the phone-making game. Given the above, is the Z3 going to tempt existing customers to upgrade? Or perhaps lure those over from other brands? T-Mobile will be stocking it this fall, though the price isn't yet known. Currently it's £550 in the UK -- a touch above the HTC One and Galaxy S5. Let's have a look, shall we?
