Pros:
- Longest battery life I've ever had in a laptop - bottom of the device is entirely battery (or maybe a GPU if you picked that one) and that's comparing it to a Haswell MBA.
- Excellent (huge) trackpad
- Studio mode is great for life drawing classes
- Face unlock just works on desktop mode
- Windows 10 is a nice modern OS (visually) and WSL /Powershell (if you want to learn it) are excellent.
- Surface Dock cable is awesome - a single magnetic charger / display / docking cable.
Cons:
- As a tablet it's too heavy.
- As a tablet face unlock doesn't work on tablet-type angles
- Silly Windows 10 apps. Like Instagram, which has a notification entitled 'Instagram', the contents of which are 'Instagram'.
- No international support - take the device overseas and need help and you're dealing with 'Old Bad Ballmer' Microsoft, who will send you back and forth between eg US and UK for years without fixing your hardware.
I'd buy an SB again, but I'd also look at the Surface Laptop (and maybe Surface Pro if someone I trust says you can type on that keyboard).
