The Keyboard on the Surface Pro 3 is actually the exact same size as the keyboard for the smaller 10.6 Surface Pro 2 or Surface 2, the TrackPad is however, larger on the Pro 3 Cover. There's just more space around the Keyboard on the Pro 3 cover.
The dimensions of the Surface 3 Type Cover are listed at 10.5 x 7.4 and the cavity of the Keyboard in the current Type covers is 10.25 x 4.2 so the same keyboard will fit although the edges would be reduced. I guess we will see if they continue to use the same keyboard or if they have to shave a millimeter or two off of it. Given that your already making a tablet with different dimensions Id think adding a millimeter to it would be a better choice than having to make a whole new keyboard just because it was a millimeter to narrow for the existing keyboard.
Bitlocker is on all the surfaces. Business customers with volume license will deploy the OS to these exactly the same way they do to their desktops and laptops. There's a deployment guide for building your own image to put into the recovery partition. You can download all the Firmware and drivers for building images and pushing updates yourself using your standard enterprise deployment/management tools.
tried convincing mum to get one... but she doesn't want to spend more than £50 on a 'tablet' lol, parents eh.
