However, the "customer loyalty" more than questionable. Parallels apparently assumes that the customer has to support the company with a year 50, is different from the "Update" does not understand politics.
Again owning 50 Update Price (V6 to V7) for a 1-yr old software with the prospect in 6 months an outdated software (back 50). All without really new features. This is also customer-friendly.
Parallels V6 way, is the only software that Mountain Lion was not capable of with me.
I switched to VirtualBox is free and enough for me.
