Laptop went when the SP3 was released. It's more than powerful enough for the vast majority of users (even the base line model), and the keyboard is more than good enough for a full time keyboard. Peoplestill seem to want to complain about the keyboard making it unviable, yet somehow I managed every single university assignment and dissertation with it and it was a joy to type on.
I will admit though, it has not replaced my tablet. But we're talking a nexus 7, because it's a completely different form factor. It certainly did make my nexus 10 redundant though. There is no denying the enhanced user experience on android or ios, but only if that experience involves youtube and replying to a forum post etc. Anything else and windows 10 is far superior, and will continue to get better with windows 10 S. I must admit it is very nice using my surface as a tablet and not having every other website in existence trying to push you over to an app each time you load a page.
Long live the surface
I think it might just be for simpliocities sake so as to be more appealing to the wider market. I know that I have to refer to it as a laptop for any of my family or friends to know what I'm talking about. Until I did that, my brother was just under the impression that it was nothing more than a tablet no different to an ipad, and was shocked when I informed him otherwise and launched call of duty.
