Re: "where your phone doubles up as an ARM-based PC to run Microsoft Office"
An idea that is then taken out at the knees by the use of the ARM processor. Don't get me wrong - it's a wonder of modern technology - but it's also the reason M$ were left with warehouses full of Surface RTs.
If I can get a 7" tablet with an x86 processor for £50 is it really beyond our best'n'brightest to come up with a phone that runs full Win10? Then you would have true continuum.
