Modern life demands that the most up to date technology also fits conveniently into our pocket or rucksack without too much bother.
As phones slim down and cram more and more power into less and less space, computers too are scaling downward but maintaining the quality customers demand.
These five models won't compromise on speed, battery life, display or aesthetic but will leave you walking round feeling much lighter.
Huawei Matebook X
Huawei's flagship new device wastes no space at all with it's 13-inch screen and full-width keyboard, packed into a package that's as light as an envelope. It is the first PC to feature speakers co-designed with Dolby, so you get Dolby Atmos immersive sound. There's an Intel Core i5 processor, 256GB of fast storage, 8GB of RAM and a battery that will genuinely take a day's worth of constant use. Available in three colours, space grey, rose gold and prestige gold.

Razer Blade Stealth
Built with gamers in mind the Razer comes with a customisable keyboard backlight, speaker grills on the sides and a neon green triskelion snake logo. Grrr. Updated for 2017 this 'ultrabook' now boasts significantly extended battery life, faster overall performance and the unique trick of being able to programme each key to light up a different colour – you can even have continuously rippling rainbow effect, should that be your 'thing'.

Dell XPS 13
The smallest 13-inch laptop on the market boasts an apparently borderless InfinityEdge display. With a 5.2mm bezel and measuring just 9mm at its end point, the XPS 13 is exceptionally skinny and light, even though the keyboard feels more substantial and solid than its competitors. It's powerful, too: the eye-watering display comes courtesy of Intel's 7th generation processors. One of the best laptops around, and one of the best-looking.
From £999, Amazon
Apple MacBook
The most up-to-date version of Apple's already excellent ultra-thin machine puts it at the top of the most-portable category, matching comfort with a weight of just 0.9kg. Add in 20 per cent faster performance with three spanking new Intel processors, and up to 50 per cent faster SSD storage and it's not hard to see why Apple's devotees remain so faithful.

HP Spectre x360
HP has upped its game with a thinner, more premium design to this 13-inch two-in-one laptop/tablet launched last year. The 360 refers to the clever hinge that lets this convertible "look good from every position", and suggests three ways of using – stand mode, tent mode, tablet mode and laptop mode. Comes with Intel Core i5, 8GB RAM, 256GB and a 13.3" full HD screen.
