I was looking forward to ML until I read the supported hardware and found that my 2006 Mac Pro won't be supported. This has happened in the past with other Macs, but this is the first time it has bit me.<p>My Pro is perfect for me, I have it maxed at 32 GB of memory, dual optical drives, and 4TB of local disk. Quad 2.66GHz cores is more than enough for me.<p>I understand that things like display Airplay mirroring depend on newer CPUs/GPUs, but ML should still be supported, just with fewer features.<p>And yes, I know this is a 6 year old system. But it's still a good solid system with a long life ahead of it. I'll keep running Lion on it until something dies (system board?) that's irreplaceable.
