Your comment really made me stop and think. You are absolutely right - Apple's iOS/OSX integration is superb, and Microsoft et al could learn a lot from it.
However, I wasn't really saying that the lack of integration was the frustration. For me, it's more Apple's direction in the consumer market and the effect that has on business use. The new phone/desktop integration with texts and calls is clever - and at first I marvelled at how my phone calls rang on my laptop etc. But in a meeting a few days later whilst presenting, and it rang even though my phone was on silent I didn't marvel quite so much. Another thing to remember to turn off in business mode then turn back on if I want it later on.
My point was more specific to how I personally use my technology. If working at home, traditionally I would use the MacBook - then after working I would pick up the iPad and go sit and use it in front of the TV. Used the Smart glass app to control the Xbox etc.. For me the iPad is a great consumer device. But then I would get a work email I needed to quickly respond to - look at a spreadsheet and make a quick edit, review a track change in a document etc. etc. and out would come the MacBook again.
With the Surface I now work in laptop mode and when finished simply pick it up as a tablet and use it in front of the TV in the same way I used the iPad. It's as good as the iPad for consuming, browsing etc. (not better mind - just as good). But for those bits of work that crop up - I can do them there and then. Workflow is just so much better. I don't need integration between two devices as I now only use one device - that's as integrated as you can get.
Phone is a different matter - I will watch Win 10 with interest on that front.
It's just my opinion, and of course YMMV - but for people who use their technology as I do then I personally think that the SP3 offers me a better workflow and more integration/flexibility between laptop/tablet/work/consuming than my apple solution did.
Some people like their technology ring fenced and prefer to keep things separate - in some ways Apple is much better if this is what you prefer. I'm not like that though. I watch a lot of business colleagues use an iPad as their out and about device and without fail they always have a keyboard case, extra bits etc. and invariably it weighs as much if not more than the surface. They then grumble when they can't do something or have to wait to get back to the laptop to finish something off.
I used to think it was inevitable that Apple would do a touch screen OSX device that would do what the Surface does - but now I'm not so sure, because I don't think they want to capture that part of the market - for them, iPad is about the consumer.
