There are several markets like for instance, the software used by enterprises which merely replace paper, and which have inflated prices. These include, software like CRM, CMS, Email, In-House Social Networks, E-commerce websites, which have very inflated prices.
For example: A recent reliable rumor I heard is a company which is willing to pay 144,321 USD for a CRM by Microsoft.
I believe the Microsoft is simply ripping people off. And there is room for competitive reduction in prices using open source supplements with maintenance costs.
Such unsound prices are keeping enterprises from investing in more advanced software.
