I needed a new Windows 10 laptop for work and grabbed both a Surface Pro 4 and a Lenovo Yoga 900 Signature Edition.
The Signature Editions come from the Microsoft Store with zero bloatware just pure Windows and are worth the added expense.
The Surface Pro 4 is a very nice tablet that functions as a laptop in a pinch (with the added type cover), I use it for taking notes in the field with the stylus, remotely operating my IR cam and showing infrared images to customers on site.
But the Yoga.
The Yoga 900 Signature is a freaking awesome laptop.
Fast, stable and relatively inexpensive for what you get when you buy it from Microsoft (I bought the i7, 16GB with 512GB SSD)
The multiple position screen makes business presentations a breeze and the tablet mode makes working on it while seated in the truck much easier than a traditional laptop.
Both of these are easily the Windows equivalent of my MacBook Air.
In fact I find myself using the Yoga more than my trusty Air for all kinds of things not just work.
BTW: Office 2016 for Mac sucks.
