HOT STUFF - ALL THE BIGGEST STORIES FROM PLANET TECH

Some people own a whole forearm's worth of watches and will choose which one to put on based on whether they're wearing a dinner suit, a diving suit or their birthday suit... but Xiaomi's Watch S3 saves you the hassle.

HOT FIVE #1

SWAP IN THE NAME OF GLOVE

Xiaomi Watch S3

When you buy one you have to choose from a black or silver aluminium alloy case, but the bezel that surrounds the 1.43in AMOLED display is interchangeable, asis the strap, so you can buy extras (prices should be affordable) and pick one to suit your threads. Like the bezel you get in the box, the blue one is made of stainless steel, but the rainbow one is infused with carbon fibre, and the yellow and green ones are both ceramic. Changing it also triggers an exclusive watch face to be displayed, so the whole look changes.

It runs Xiaomi's HyperOS operating system, which works with both iPhones and Androids; and there's no shortage of sensors underneath, including dual-band GPS and a 12-channel heart-rate monitor with SpO2. Over 150 sports are supported, including skiing and snowboarding, although it's probably best not to do those in your birthday suit.

HOT FIVE #2

RUNNING A QUICK 8K SAMSUNG QN900D

When it comes to watching video, bigger is always better. At least, that's the theory.

Drives to move beyond 4K and onto 8K have stalled, leaving super high-resolution to outfit like IMAX and its 70mm offering.

But since you can't have that here at home, you could investigate Samsung's 2024 TVs, the crown jewel of which is the 8K QN900D. Yes, we know that 8K content remains scarce and we also know that you'll watch (mostly) 4K on this set unless you're giving a demo of what's possible for any jealous visitors. But there are benefits to having this many pixels, thanks to Samsung's software wizardry. And a few extraneural networks. 512 of them, in fact.
