Mac household here, for decades. iMac, a couple MBAs, MBP, iPhones, several iPads, and quite a few ATVs.
We just bought our 2nd Surface, today. This was to replace my woman's 2012 MBA 11 that finally took a dump. When looking at all the options, she liked the small size and tablet capabilities of the Surface 3 (non-Pro model). She only uses Office a bit, and spends most of her time consuming content. For her, this works.
I also have a PS3 that's giving my iMac 27 and MBA 13 a serious run for its money. It blows away my MBA in the performance department, and keeps up with my 2012 iMac 27. When I have it docked with two 27 high res display, I'm lacking for nothing.
But the biggest thing for the way that I work is being able to immediately switch from casual consumption to serious creation. Now, if I get a work email with a PPT or Excel attached, and can view edit and distribute without even getting up. Yeah, there are iOS versions of Office, but they just aren't the same and have formatting issues.
Continuum is a dream in the way it switches from tablet mode to desktop, automatically when you remove the keyboard or flip it to the rear.
Win 8 was awkward. Really, I saw where they wanted to go, but I just couldn't get there with them. Win 10 is outstanding! It's designed for the way that I want to work. It does take a bit of getting used to, after a couple decades mostly on the Mac. But once you get the hang of it, it's very efficient. My Swag is, as a desktop, it's probably about 95% as good as OSX. As a tablet, it's probably now about 85% as good as IOS. But doing both is priceless! And every Microsoft update seems to notch those percentages forward.
And even the prospect of being able to plug my phone into a KB/Display to edit a big excel spreadsheet, while on the road... Whoa!
Oh, and people who are saying that touch capability on a laptop is a gimmick haven't lived with it for a while. It's that capability that's caused smudges on my iMac and MBA, as I keep touching their screens in vain attempts to scroll windows or pinch them... LOL
Started working for a Mac software company in the early 90's and have been a fanboy since, but color me impressed!!!
BTW, while the MS announcement was stellar, my SP3 is still good enough for me, at least for the next year or two. After that, I'll probably replace it with another SP Pro. While the Surface Book is interesting, batter life is too short when it's in tablet mode. Then again, maybe when I see it in the flesh I'll change my mind and wish they had had bought one, and gifted my woman my SP3? LOL
