2017 will be even bigger. The more users you have - the more malware you get.

For example suppose you have only "1" malware for your OS. Next year you have "2", a 100% growth rate.
Now suppose you have a shitty OS with 1000 malware. Next year it has 1200 malware, a 20% growth rate.
Someone without this knowledge would go about and claim the second OS is "safer", but the truth is both OS's are just experiencing an exponential growth rate, the first OS is just at the first stages of the curve.
I shut down my Windows 10 Laptop before leaving work yesterday. I forgot to sign into the newly setup wifi. So I connected my Windows 10 phone to it.
My Windows 10 phone has my Windows Live account on it. As does my Windows 10 Laptop.
Today, I logged into my Windows 10 laptop using my Windows Live username and password, and yesterdays WiFi settings (that I setup on my phone) instantly sync'd with my Windows 10 laptop.
At the same time, my Onedrive account sync'd all the files I'd been working on last night, on my Windows 10 desktop.
You can get the same 'least amount of work' experience if you fully invest in the Microsoft ecosystem (onedrive.. live.. etc..).
MS was the last to implement it though...
Peace
