Mountain Lion update page confirms incompatibility with older Macs
As first hinted in February, Apple's upcoming OS X 10.8 Mountain Lion operating system update will not include support for certain models of Macs with older Intel chipsets with integrated graphics.
A "How to Upgrade" page on Apple's website (via The Verge) contains a list of Mac models that qualify for Mountain Lion:

Apple announced OS X Mountain Lion in February, specifically mentioning newer Macs as qualifying for the upgrade. At the time, it was suspected that Macs with Intel's GMA 950 and GMA X3100 integrated graphics processors would not be capable of running OS X 10.8.
By distributing new versions of OS X solely on the Mac App Store, Apple has also drawn a line in the sand, since Macs not capable of installing at least OS X Snow Leopard 10.6.8 won't be able to access the App Store.
The Mac maker appears on track to release Mountain Lion this month as promised. Developers received the Golden Master version of the OS on Monday and an invitation from Apple to submit applications for the update to the Mac App Store. The $19.99 upgrade contains over 200 new features, such as closer integration with iCloud, new security checks and voice dictation.

- iMac (Mid 2007 or newer)
- MacBook (Late 2008 Aluminum, or Early 2009 or newer)
- MacBook Pro (Mid/Late 2007 or newer)
- MacBook Air (Late 2008 or newer)
- Mac mini (Early 2009 or newer)
- Mac Pro (Early 2008 or newer)
- Xserve (Early 2009)

That's where you can learn everything. How to upgrade is just… how… to upgrade.
so no black macbook?
I am going to have one splintered OS family in my household.
My 2006 MacPro 1,1 will end its journey at Lion. My MacBook Air currently runs Mountain Lion (DP). However, I need to keep my company MacBook Pro at Snow Leopard.
I'm sure all those cats will get along.
I've an idea for 10.9.
Snow Mountain Leopon. Works sort of like 'Snow Mountain Syndrome'.
Take the best things about Mountain Lion (feature set) and the best things about Snow Leopard (it's wicked fast and incredibly optimized) and combine them. One last spectacular hurrah for the mouse+keyboard combo before…

I'm in a similar boat. My original intel 20" iMac's last eligible upgrade was SL...no Lion or ML for me. I do have an iP4s and an iPad 2 though.
I recently went into an Apple store to look at my website on an iMac and I have to say...the subtle changes to the OS in Lion, Safari, etc., are really neat. But I don't think another iMac is in my future. Maybe an 11" MBA though. Shame.

The "How to upgrade" page also tells users how to check which Mac they have so they know if they will be able to upgrade.

I love my iMac much more than my Air- but of course, I sit at a desk 95% of the time. The cloud features are fantastic if you use your contact and calendars often. I use them daily for business, and I can't tell you the convenience I now have updating client information in my address book, and my wife scheduling my appointments (or telling me when I have to be at a family function) on my calendar.

No way.
OSX 10.9 Liger!
Also: what amazing new graphical improvements are to be found in Mountain Lion versus Lion, that would make 2008 models no longer compatible? Aside for the ridiculous and useless notification bar, what's changed?
Anyone running Mountain Lion here?
Is it snappy and optimised?

I got it on close-out in early 2008 and saved several hundred dollars, but at the risk of getting something a tad out of date (it was superseded by an identical-looking MBP with a minor processor spec bump). In this case, my MBP meets the minimum requirement. Still a great laptop.

There's only one logical choice for OS 10.9:

Running the GM of Mountain Lion now on my 2009 13" MBP, and while it's not what I'd call snappy, it's miles ahead of Lion in the fact that it doesn't crash every five minutes, and it seems like they've finally fixed that photo scrolling bug, in which pictures would go all whacky while scrolling down the webpage. The best analogy I can come up with is Mountain Lion is to Lion what Windows 7 was to Vista.
The only real annoyance is the new Sandbox architecture for apps, which while good for security in the long run, sucks right now because most apps haven't been updated to support it. Case in point: Toast can't see my superdrive, so I can't burn DVD's at the moment. Once the program API's are updated, everything should be right as rain.
Cost to Apple to update integrated graphics drivers to 64-bit: $50,000
Cost to 1000 customers forced to upgrade their still useful hardware: $1,000,000
Benefit of this policy to Apple executives and shareholders: $1,050,000
Apple to customers: "Screw you."
Customers to Apple: ?????
I also liked that black hole for the trash icon in the NeXT OS.
