While lighter and more svelte than the Xperia Z2, which only came out a few months ago, the Xperia Z3’s remarkably similar to earlier Xperia Zs except for one particular new feature…
Sony's unveiled its latest Xperia Z flagship smartphones, the Xperia Z3 and Z3 Compact - the first ever mobiles you can play PS4 games on.
The two new arrivals come less than six months after the arrival of the Xperia Z2, which could annoy those who've signed a 24-month contract to get one, because if Sony continues at its current pace, we'll see an Xperia Z4, Z5 and Z6 before the next time they're free to upgrade.
On the other hand, aside from the fact they're slimmer and lighter, the Xperia Z3 and the adorable Compact version are good examples of Sony's 'if it ain't broke, don't fix it' way of looking at things, as there's only one new feature that stands out.
And that is that both the Xperia Z3 and Z3 Compact can be attached to a PlayStation 4 controller, allowing you to 'remote play' whatever's on your console i.e. you can play PS4 games on the go.
Both phones come equipped with all the Xperia Z2's great features, like its powerful 20.7 megapixel camera and being completely waterproof.
Sony's president and CEO, Kunimasa Suzuki, said: "Consumers demand and deserve greatness from their smartphone - in design, camera and battery life.
"That's precisely what we aim to deliver with Xperia Z3 and Z3 Compact, at the same time delivering leading innovations such as unique Sony camera experiences and, for the first time, PS4 Remote Play in two beautifully designed, fully waterproof smartphones."
And now for the technical nitty-gritty. The Xperia Z3 boasts a massive 5.2in full HD screen, while the Z3 Compact has a smaller 4.6in but identically crisp display. Both are powered by a 2.5GHz processor, plus 3GB of RAM in the case of the Z3 and 2GB in the case of the Compact.
If you've got an Xperia Z2, you're not really missing out on much - apart from PS4 Remote Play - so don't fret if you're unable to upgrade for the time being because you're tied into a lengthy contract.
One way to avoid this situation in future, and ensure you're always able to get the latest phone if you want it, is to sign up with O2 on one of its O2 Refresh plans.
By separating the monthly cost of calls, texts and data from the cost of your handset, O2 Refresh lets you upgrade to a newer phone whenever you like.
