Having tried a Surface Pro 3 for both work and leisure, I’ve come to the conclusion that Windows 10 is more schizophrenic than being 2 great superheroes in 1.
For work: I couldn’t work out how to access the desktop in Tablet Mode. And that is significant because the desktop is a shortcut space for me to access folders and short-term files (e.g. PPT to show at the work conference).
And for the love of everything sacred you cannot find anything online because ‘desktop’ happens to be the name of other Mode in Windows 10 – so any search just returns oodles of results about the ‘great’ feature of being able switch between Tablet and Desktop Mode.
For leisure: as previously mentioned, Windows 10 doesn’t pop-up the onscreen keyboard for Firefox (yet) automatically; sure, not entirely the fault of Microsoft, as Mozilla probably hasn’t updated Firefox to be fully conformant to Windows 10 – but still, its annoying.
