A Lenovo E460 at reasonable configuration is about 1/3rd the price. In November 2016 it offered Win10 and optionally Win 7. Linux runs just fine.
The Surface laptop is let down by MS worst OS since ME and x3 too high price. At least with the Apple tax you get a reasonably decent OS (though not as good as it used to be).
All those evil privacy and bandwidth stealing features by default. Almost zero customisation of GUI. So integrated to cloud that you get "complaints" in Notifications if no internet.
I have Win 10 desktop and x86 Keyboard Tablet for test purposes. All that Iot, peer to peer, cloud, phone and telemetry garbage on by default in "Services". "Quiet Hours" can't be more than 12, cabled ethernet can't be set to metered, though WiFi can. I'm rural with a capped fixed wireless modem/router connected to my wired 1Gbps ethernet. Some areas of property have unusable WiFi.
