Microsoft's gap
While Microsoft does produce an "Office" for iOS it is a diluted product. For instance, earlier versions could not run macros (I am not sure what the current situation is) and it does not have the basic - menu shortcuts, e.g. -F for "File". In any case, the quality is not consistent over the different M$Office products (Word is nowhere near the quality of Excel). Other products, like Libre Office and Open Office have filled the gap to some extent, but not fully. An enterprising software publisher could target this gap. Microsoft did best when most computer users were computer semi-literate. As computer skills have grown, their FUD advantage has diminished. With the growth of "Bring Your Own Devices" the buying decision is shifting from IT departments (where once "no-one ever got fired for buying IBM") which tend to favour the Microsoft corporate marketing pitch to the users, who favour user-friendly products (and what their brother-in-law, neighbour or kids have on their smartphones or tablets).
