After reading the comment of Jie Sun, I agree and also disagree with it.

The Office 365 Mobile Apps has been given away, which is unfair to those customers who has paid for it. We all know that this is not cheap. Maybe Microsoft wants to choose the cost leadership  strategy, but The free Office will decrease the customer loyalty.

On the other side,  Jie Sun said that it is in convenient to use mobile phones and ipads. I hold the different opinion. Most computers are too big and heavy . It’s  hard for people to bring them to everywhere.  However, these ipads are different. They have less sizes but more functions. What’s more ,there are more people who haven’t paid  the fee than those who have paid. Consequently, Microsoft should choose the majority of market segment and ignore the emotion of old consumers.
