Microsoft wants us to pay for software according to usage

Since a long time in the trade, some have realized that the best means of gaining more money was not to sell, but to rent. Thus, the customer is never owner of that which he uses and must indefinitely continue to pay to have the use of it.
After having proposed X versions of Vista, Microsoft will try to apply this process to data processing.
