It looks tremendous – a perfect balance between small body size and big screen – thanks to the tiny bezel that runs round the display.
This bezel is nothing compared to the wide silver frame around the display which was required when the first model arrived.
The connectivity has been updated too.
There’s no SD card slot – no USB-A ports and no wonderful MagSafe power connector.
Only the headphone socket is carried over to the new laptop.
What’s new is the same Thunderbolt 3 USB-C connector found on the MacBook – used for data transfer and charging.
Except this laptop has two of them – which is a very big improvement.
It’s not the super-useful four sockets that are found on the MacBook Pro but it’s a very welcome upgrade.
The other visual difference is the trackpad – which is noticeably larger on this new laptop.
And it’s a Force Touch pad that is – it gives the impression of moving when it’s only a persuasive haptic feedback that’s fooling your finger.
This is one of the most noticeable changes to the laptop – once you’ve stopped admiring the thin dark bezel and all-glass covering that succeeded the silver aluminium frame.
The 13.3-inch screen is now – finally! – a Retina display.
Instead of the 128 pixels per inch (ppi) on previous similarly-sized MacBook Air screens this has leapt to 227 ppi.
To say this makes a difference is an understatement.
Actually it’s more that if you used the MacBook Air it was fine until you glanced at a recent MacBook or MacBook Pro with their glorious Retina displays and then you simply didn’t want to go back.
Now the MacBook Air has joined the Retina club.
It’s unquestionably the upgrade Air users waiting to replace their laptop have been aching for over the last few years.
There are more colours available on this screen – 48 per cent more Apple says – and in this respect also the improved display is a big step forward.
