What is the MacBook Air ?
The new Apple MacBook Air  has finally arrived. And by “finally” I mean MacBook Air  has given this much-loved laptop an accurate update, instead of the iterative upgrades we’ve seen with the past few versions.
As well as better Retina Display, which packs a resolution of 2560 x 1600 into a 13.3-inch panel. There’s the T2 security chip, which automatically encrypts your files and offers a secure boot option. That latter is likely to be mainly of interest to IT professionals, sysadmins or whoever buys the laptops for your company.
The MacBook Air has a 13.3in screen, but this time there are four times more pixels – that’s 4 million pixels (a 2K display). Resolution 2560×1600 native resolution at 227 pixels per inch.
The screen expanse almost to the edge of the display thanks to bezels that are 50 percent thinner, the MacBook Air is smaller than its predecessor, despite having the same size screen.
It’s also tiny than the previous model, weighing in at 1.25kg or 2.75lb (compared to 1.35kg for its predecessor).
The new version of the Apple MacBook Air  measures 0.41-1.56cm x 30.41cm x 21.24cm. It has as like wedge design to the original model. Apple says it’s 10 percent thinner than the previous.
Keyboard & Trackpad
Might be it’s all about Face ID on the iPhone and iPad (see our story about the new iPad Pro) but it’s all about Touch ID on the MacBook Air. Apple’s added a Touch ID scanner in the top right corner so that users can pay for things using Apple Pay as well as unlock their Mac using fingerprint recognition.
Below the new butterfly keyboard – described by Apple as the third generation butterfly keyboard – there is a larger Force Touch trackpad offering 20% more surface area than previously.

Why buy the MacBook Air 2018?
If you’ve been waiting patiently for an upgrade to the previous MacBook Air, then it’s no contest – this is a significant update that hugely improves on the softly-softly iterations we’ve seen over the past few years. The small bezels and low-res screens are gone, replaced by a much slimmer, smoother machine with a high-resolution Retina Display panel.
