I'm about to pull the trigger in a new Mac but have a question: is it possible to downgrade ML to Lion? I remember when Lion came out that if a Mac already had Lion you couldn't backdate to Snow Leopard but if you upgraded SL to Lion you could backdate to SL. As we all know all new Macs are coming with ML and not all of my apps are updated to work in ML. Previous Macs around here have Tiger and SL. So I don't have a copy of Lion around which raises another question: is Lion somehow available from the App store or do I have to go third party to get a copy of Lion (assuming I can downgrade ML to Lion)? I've seen several things on the web about backdating ML to Lion but those were only if the machine in question had been upgraded to ML from either Lion or SL.
