I just want to clarify my point with continuum and how it similar to Windows RT. The miss communication in my opinion is "Turn your phone into a PC". It can't do what is implied. It is only currently supported on a tiny number of universal windows platform applications. Just like with Windows RT, you can't run PC applications. If you are in PC mode, I don't see the problem with having a Win32 desktop, virtual or real. I'll have to check out what they have done with the X3.
Having an awful UX doesn't help like you say and they are making progress in some ways. I can see how UX can be a big factor for some people including me. I haven't bought a 950 because of the UX. I personally consider the UX on w10M to be a step down from 8.1 except for the settings and notifications area.
I don't use Office personally but I can imagine that not having a touch based version on windows RT would be pretty bad. Putting a preview OS on the 950s was probably not a good idea either. I'm a bit bewildered by it all.
I disagree, Continuum and RT are no where similar they may be similar where the lock down is but that is where the similarities end.
RT, i'm sure you are aware was the Runtime used by Windows 8.x without the Win32 functionality, therefore it was much robust in terms of gestures, multitasking and so on.
You cannot at present snap anything with continuum but are limited to full screen mode similar to how apps used to open in the full content glory on Windows 8.
Continuum will obviously continue to evolve as mobile chips become more and more powerful to be able push insane more data and pixels at the same time. Most people don't realise each individual pixel does contain data and the cpu/gpu is constantly processing that data as each pixel changes.
For example so when you combine a 4k display which is playing a movie in native resolution, playing games on your phone, whilst you are downloading something via Ethernet onto your phone without it breaking a sweat; that is when you know you have a incredibly powerful device on your hands.
In terms of App visualization, we will need to wait and see what happens as it is the first time an OEM has bundled their own visualization solution, with windows mobile 10 and along with continuum support.
