I use USB 3.0 devices quite often. W7 doesn't manage those well at all (mostly because it has no built-in support--you're completely at the USB chipset vendor's mercy, and most of them do a really shitty job).
I wish Apple had more compelling portable hardware offerings. As much as I like macOS, I'd have to give up a lot to switch to it. I'm probably not in their target demographic, but I don't want a thin, light laptop. I want one that's literally just like the one I have, just running macOS. And no, I don't consider making it into a hackintosh to be a valid option.
I'm pretty much stuck on Windows when it comes to my gaming rig (and Linux gaming is still a pretty hilarious joke), but I'm not too bothered. That's far from a critical system.
