I bought my SP 2017 to replace my SP 2, which is still trucking along just fine. I am a Real Estate Agent and I just couldn't see myself lugging around my 15 inch HP Envy. My SP 2's screen is too small to do any prolonged serious work on it, but the SP 2017 is perfect. I tried to use my iPad Pro for work, and found it was very frustrating trying to make apps replace full blown computer programs. The SP 2017 is so much more versatile, in that it runs a full PC OS. Not even a second thought when I work on it. It just does what I need it to do, like a real PC should. Don't get me wrong, I like my iPad pro. It's a beautiful piece of hardware, but it ain't no PC replacement. I can't see getting a Surface Book, as cool as it would be to have one. The SP 2017 just does everything I need it too do just as well, and has a smaller footprint to boot. Job well done MS.
