This not Linux its supposed to be the giant Microsoft that supply the 64bit emulator, My concern is that they are still selling the surface pro x with only 32bit support when they themselves no longer support 32bit anything.
They are selling a product unfit for purpose.
Millions of users of windows use Intel processors, Arm has very little support from software developers at present hence the most urgent need for 64bit emulation.
As I said previously this device at present is widely unsupported with only store apps its no better than RT.
The problem with this is MS have total control over the device life expectancy as with RT which is not an old system being based on Windows 8.1 but is now completely unsupported and not even a working browser.
Perhaps with this in mind you will see just what the future without an emulator could bring.
If you don't own a surface pro x I really cant stress enough DO NOT buy one.
I'm still having stability issues and crashes and support are less than useless, if you want a fast reliable tablet buy Apple iPad Pro, I have own both of these devices for the same length of time and I have had not one problem with the Apple device and constant problems from day one with the pro x
