I have a Mid-2010 2.93 i7 with 12 GB of Ram and 1G Graphic Card. Purchased it in 2011. It's just over a year old and you're telling me I now have to look at specs to see if my mac is capible of running new software???

Typically I only go to support if I'm having issues with a product. Too little too late - I upgraded it!

I had to read it twice to find "Mid-2011 or newer", and I knew what I was specifilly looking for (it's the grey little number 1 after Air Mirror)! Why did Apple decide to hide it with a fine print disclaimer that it's not going to work on the majority of the macs out there!
Why are you HIDING IT!!!
I would have upgraded to Mountain Lion regardless to stay current with the OS regardless. For $20 it's a great deal. But Air Mirror was really the only feature I was looking forward too.
I'm mainly upset that Apple was not up front with us on Air Mirror. When you advertise this great new feature you're going to have on your mac running Mountain Lion, and find out later when you're wondering why the Air Mirror icon doesn't appear on your screen.....you know what comes next. You can go to support, but too little too late (see what I meant).
I almost went out to purchase the HD Apple TV prior to ML just to run this feature. Glad I didn't (you would probably have seen more postings from me if I did).
I understand that the next generation macs will be faster and have better technology (i.e., Retina Display), that's technology. I would even understand if my mac was 5 years old and some features didn't work. But to not be able to support a product after 1 year, that's rediculous!
Just be up front like the iPhone, it won't support flash - we as consumers may not like it, but we know what we're buying and getting ourselves in to when we make the purchase.
