I watched a 14in laptop transform into a 17in one at the press of a button, now my MacBook Air seems inferior

Lenovo is a dab hand at creating concept prototypes – which is exactly what the PC-maker was showcasing at its Innovation World event, set in tandem with the IFA technology show in Berlin.

Having already seen the future of laptops in its fanless solid-state cooling concept, the AeroBlade, the brand's other laptop concept was a familiar idea – but impressive nonetheless.

Under the Project Swan Concept moniker, this latest laptop prototype is able to transform from a 14-inch 4:3 aspect ratio into a 17-inch 16:9 panel at the press of a button. Quite literally.

That's down to Lenovo's ongoing work with rollable display types, which use the benefit of OLED's flexible potential to its fullest extent.

Here, the laptop is a little thicker than normal, but even so that expansive screen scale made my 13-inch MacBook Air's1 16:10 aspect screen just seem inferior.

A simple press of the Insert key along the device's F-keys row activates the display's expansion, no other prompting required. It forms the new widescreen format in mere moments (complete, for this demo, with an animated swan ).

I can see why this is still a concept, however, as close-up you can see the flex in the rollable display. And there's always the risk of dust and grime causing damage across the rollers and the display itself.

It's not the first time that Lenovo has shown off expanding displays, of course, with the CES show in Las Vegas earlier this year showcasing the brand's Legion Pro concept – which expands into 16-inch gaming laptop.

Project Swan, however, just seems more feasible. It's better balanced than the Legion Pro concept was, for starters, and while the thickness is more than your average to cater for that roll-back display, it's still portable overall – at 17.9mm total.

With each new step in its rollable concepts, Lenovo is clearly working towards a conclusive, shelf-worthy product that you can actually buy. This one isn't that, but it shows yet more progress towards that goal.

So, who knows, maybe come 2028 we'll be living in a world where you needn't pick the 13-inch or 16-inch model – you might be able to buy a single device that caters for both. And all at the touch of a button.
