Lenovo has such a machine, but I don't know what the keyboard is like. Having said that, the keyboard which goes with the Surface Pro 3 is very good, and the keyboard which goes with the Surface Pro 4 is excellent. You have a magnetic locking system with these devices, and that feature works really well. Means you have nothing to fold back or the like, but that you can use the device as a proper tablet when you want, and as a proper laptop when you want.
