i have immediately thought of that. Also Microsoft has Office Apps for Smartphones. I downloaded them once, but never used them. For a quick view a browser based solution would be sufficient, i really don't need full editing capabilities on my smartphone.
Speaking of tablets is entirely different, but microsoft already has the surface computer/tablet mix.
I use Word on Android + the MS fold-able mobile keyboard (pic in the article) to edit documents a lot. It works well for me on my P8 max. I am not the average user but I can't wait to never need a laptop or tablet again and just take my phone (or, better yet, clam shell) and fold able keyboard.
Why can't there be a smartphone/tablet/desktop mix? With a single device, so that your apps are always running, you're always in the same place, all your data is always there (connectivity or no) etc.
ASUS actually already tried a smartphone/tablet device with PadPhone, but it lacked the productivity angle that full-fledged Win10 would bring to the table. Also, I think the idea of physically docking the phone into the tablet is counter-productive, because it results in a bulky device, and you cannot use the phone.
A simple tablet that is basically just a wireless display with touch makes a lot more sense, and the phone can stay in the pocket. I also wonder how much lighter the tablet could be made if it didn't have to have a powerful chipset, and cooling for it.
