I'm very happy with the SB, Windows has been great, and the SB is a wonderful machine. The fit and finish definitely remind me of Apple in terms of quality.
That's the issue I see right now, Apple's competitors have caught up and are producing some really nice products, Apple can no longer just rest on their laurels
I've been using the SB while on a business trip and its been really great. I've watched movies (in my hotel room), taken notes, remoted into the office, running office apps, I'm not saying the latest Mac can't do that, but I'd rather spend 1,000 on a laptop that is Skylake, touchscreen, removeable screen, then a Broadwell based MBP - YMMV but I found value in the SurfaceBook, and so far I'm not finding value in Apple's line up. That will change once (I hope), once they roll out the updates
