Problem is Mountain Lion and not the upgrade price of GA. It is impossible to have an upgrade plan that considers every case. There has always been and will always be upgrades that unfortunately puts people in this situation. I am in the same position as you when it comes to Mountain Lion. I regret upgrading from Snow. What is more unfortunate is that GA4 is not at all the same product as GA3. It is not an “upgrade” but a totally different drum software. GA 4 should not have been given the same name. Many people are pissed as they thought they were buying an upgrade.
