I think the surface line of kit is great from a usability standpoint when it works. The problem is its had so many issues with updates that its a standing joke among IT pros. We had a few of them in work and whilst users love them they end coming back and swapping for normal Lenovo X series laptops as they are just too unstable.
The surface book well they all came back and now the cover not working on the pros...............
Can MS actually fix the fault - even rolling back the firmware would be great until they can fix it properly but I guess that is not possible......... what a shambles.
