I use my SP2 a lot with the Pen and OneNote, which provides automatically digitized handwriting that is viewable and searchable from any computer. It's a pretty killer app but I would probably still be using pen and paper notebooks before someone integrated a screen and highly accurate pen in one device.
You may find some uses for the tablet that you never imagined before.

The lack of USB-C surprised me a bit, too, especially as they said 'we only stopped going thinner because we wanted to fit USB', i.e. they're claiming they could go even thinner without compromising anything except losing USB, which is where USB-C would've done the trick. Anyway I probably would've gone USB myself, too, there's just too much stuff out there for existing laptops using USB. But instead of the charger, why not offer USB-C as a charger, alongside the regular USB ports? The charger could then connect to a new docking station that'd give you both charging as well peripherals like a monitor, mouse and keyboard office setup. That way you could push USB-C forward, create an easy charging and docking setup, maintain the old USB ports this generation (thereby not excluding anyone), while also facilitating those who buy new USB-C peripherals because they actually work on the Surface Book, making a full change to USB-C in the future (Surface Book 2 or 3) easier, which would then allow an even thinner device. I mean I get they built a cool charger and docking solution and it sucks to ditch that but I don't see the advantage over USB-C.
