My experience concerning the typing 'severe lag': MS Excel on iPad is excellent - the problem is MS Word on iPad. It's not just when typing in Tables and it doesn' t matter which font I use - it is just 'severely' slow and unacceptable !!
Even more unacceptable is MS's extreme reluctance to even address the problem, or respond, despite it being raised over a period of some time by many (and not all computer-illiterates like me!).
I manage the typing delay (although it's not quite prolonged enough to stop for tea!) but it is looking more like I might revert to CloudOn which I used to use.
For anyone in MS reading this - any chance of some sort of action/response?
