I can understand the need for the upgrade should Parallels be adding new features to take advantage of Mavericks, however it seems to me Parallels sees a revenue opportunity and it is using its leverage on the customer installed base. Simply to instruct users to send 50 dollars to get it to work is subject to ridicule. !
