Microsoft today unveiled not a smaller Surface Mini, but a larger Surface Pro 3 Windows 8 tablet. It has a 12in screen to match the latest Samsung Galaxy Pro tablets, and comes in a thinner, lighter chassis that makes it more easily portable than a MacBook Air. According to Microsoft, the Surface Pro 3 is the tablet that can replace your laptop. Here we look at new features in the Surface Pro 3.

New features in Surface Pro 3: Performance
Microsoft claims its Surface Pro 3 now has the "power, performance and mobility of a laptop in an incredibly lightweight, versatile form". With a fourth-generation Intel Core Haswell processor and up to 8GB of RAM inside, the new Surface Pro 3 is able to run even intensive programs such as Adobe Photoshop. Microsoft says it's now 10 percent faster than the Surface Pro 2.
New features in Surface Pro 3: Screen
Microsoft has increased the size of the Surface Pro 3's multitouch screen. Previously a 10.6in (1920x1080) ClearType panel, it now measures 12in with a resolution of 2160x1440 pixels. Despite this, the Surface Pro 3 is lighter than its predecessor - 800g vs 1kg - and has gone down from 10.6- to 9.1mm in thickness. Indeed, the Surface Pro 3 is the thinnest Core PC ever made, according to the company.
New features in Surface Pro 3: Surface Pen
A redesigned pressure-sensitive Surface Pen lets you draw, write and generally get creative. Now clickable, a single click of the Surface Pen opens OneNote and lets you begin writing even while the Surface Pro 3 is asleep. A double-click takes a screenshot and uploads it to OneNote.
New features in Surface Pro 3: Kickstand and Type Cover
There have been updates to the Surface Pro 3's kickstand and optional £109 Type cover, too. The kickstand is now able to be fixed in any position, and with improved 'lapability' a double-fold hinge lets you lock it to the display's lower bezel for easier working with the Surface Pro 3 on your lap.
The optional Type Cover is thinner; combined with a 68 percent larger trackpad, typing on a tablet is for the first time an enjoyable experience. New Palm Rest tech means you can even rest your hand while you write without it moving the cursor elsewhere on the screen.
New features in Surface Pro 3: Other specs
The Surface Pro 3 supports the latest 802.11ac wireless standard, as well as Bluetooth 4.0, USB 3.0 and Mini DisplayPort. It has built-in front- and rear-facing mics, 45 percent louder stereo speakers with Dolby Audio-enhanced sound, and two 5Mp cameras (front and rear) that can capture full-HD video.
A redesigned fan is 30 percent more efficient than any other. It's apparently silent, with no airflow obvious through the perimeter vent.
New features in Surface Pro 3: Windows 8.1 Pro
Running Windows 8.1 Pro, you can install any Windows program on the Surface Pro 3 - not just apps from the Windows Store. This means it'll do everything your Windows laptop can, and in a smaller, lighter, equally powerful shell. With battery life said to last up to nine hours (web browsing), that's not at all bad for a workhorse laptop.
