For one, Mac OS does multiple displays and DPIs right. The trackpad is also solid. Plus the unix stuff that's always been there and isn't some subsystem only available with certain versions of windows. Also, the boot up and sign in process sucks in Windows vs Mac. Once I'm given a mouse cursor post-signon I'm ready to go in Mac OS. With Windows, I've got to wait for the AV to load up and do it's "routine". Then there's the probability of Windows Updates working the first time.

And then there's the Windows telemetry stuff. Apple's actually talking about ways to incorporate identity anonymization (sp?) into its browser. They've stayed out of trying to reap side income off device usage in multiple ways.
