Well it happened. SP4 lost it's life last night and since warranty was out decided to go with the Surface Book i5 128gb. Downgrade on the storage but that's all. Kicking myself for throwing away all the adapters for my micro SD card now lol.! Currently upgrading to 1809. Would have been nice if the Surface Image was 1809 but came with 1709. I can say this is the first time ever that I have bought a laptop and didn't even consider Apple. The Surface Pro 4 was my first Windows laptop since 2000. Impressed so far but will take a little bit of adjusting. I actually used my SP4 as a tablet 90% of the time. Could have been fine with a SP4 again but wanted the slightly larger screen.
