I have read several people asking about OS X Lion and fearing it will not run on Core 2 Duo MBAs. Apple updated its Lion page and shows system requirements of Core 2 Duo. That simply means it will be a 64-bit CPU required. The only Macs with Intel CPUs that will not run would be the 2006 Core Duo models. People shouldn't panic or expect any model MBA wouldn't work with Lion. Apple isn't going to terminate OS X support as quickly as it does iOS support. I think that iOS is why many people are wondering if they buy an 11" MBA with C2D if it will really even be upgradeable to Lion. Happy days, everyone. A month away from a nice upgrade for a mere $30. Who else is looking forward to all of the new features?
