Microsoft's new tablet-cum-laptop was officially unveiled following months of rumours, outed on stage at the company's big product launch event today.
The device is the first hybrid designed by Microsoft with Windows 10 in mind and, as such, is also the first to tout the new OS at launch.
The new Surface Pro has a 12.3-inch PixelSense display – up from 12-inches – with 5 million pixels and a 267ppi pixel density.
In terms of performance, Microsoft expicitly claims the Surface Pro 4 is '50% faster than the MacBook Air', thanks to the i7 CPU on board.
"The MacBook Air is a great, great product, but let's just compare it to give you a sense," explained Panos Panay, Surface and Lumia VP, announcing the product.
Panay also revealed that the Surface Pro 4 is 30% faster than last year's Surface Pro 3.
Customers can spec out their device up to a maximum of 1TB of storage and 16GB of RAM.
It's more svelte than the last version at 8.4mm. Microsoft also says the Surface Pro 4 has the thinnest Type C cover yet.
A new addition to the series is a fingerprint sensor, which should boost security on the platform.
The trackpad is 40% larger this time around, and offers 5-point multi-touch. The keyboard, meanwhile, is backlit.
The device also ships with an 8-megapixel camera for video calling, or just taking selfies.
There's also a new magnetically-stored Surface Pen, which has a one-year battery life, 1024 levels of pressure, and an eraser on the back.
There are five colours of Surface Pen on offer, and Microsoft has confirmed that there will be interchangable pen tips to suit varying use-cases.
