I feel like users who paid to upgrade to Lion are getting ripped off. I upgraded to Lion because I am a huge apple supporter and loved the idea of a new OS for $30. Now with the release of Mountain Lion just a short year later, I'm regretting my decision of purchasing OS Lion. Now if I want to get 10.8 I will have to pay $50 while those who didn't upgrade only pay $20. I at least expected there to be a discount for Lion users. Any other Lion users regretting the upgrade?
