I've found that I personally have a great deal of cognitive dissonance when it comes to pricing for MS Office. On the one hand, I hate the idea that software that I used to pay for once and have forever I now rent for a potentially greater sum over time. On the other hand, I spend more time in MS Office than any other software I own, except for a web browser (which is usually productivity-detracting, not enhancing). People don't mind paying similar amounts for cloud CRM or project management systems that offer pretty basic functionality, but don't like the idea that Microsoft would move to that model with a much richer offering.
