Yep. I run latest Ubuntu on my Surface Pro 4 and it's great. The touchscreen doesn't work, although there are plenty of custom kernels out there that would fix that.

Doesn't that eliminate one of the primary draws of the platform? I love taking notes and whiteboarding on my SP3.

You still like the Surface Pro enough with the touch screen not working? One of its biggest draws? That's seems quite nice. Major points in the Surface series favor.

Oh this laptop was bot detachable and didn’t have touchscreen!

Man, I would have bought it in heartbeat.

I don’t reason why Microsoft pushes touchscreen anymore. Considering their Win10Phone is dead already as they are the one admit it.

So we have detachable Surface Pro which is great. But we can a surface laptop without touchscreen, on it.

There's a surface laptop without a detachable screen, it's called the surface laptop. It does have a touchscreen but if you don't want that just don't touch it. You can even disable it permanently in device manager if you like
