Ad network: OS X is becoming fragmented
Summary: The issue is that developers will have to code their apps to work with four major versions of OS X to be compatible with the largest number of Mac users.
Online ad network Chitika Insights has some stunning new data about the fragmentation of OS X. Its latest report on Mac OS X version distribution contains some notable findings.
OS X Lion/10.7 (28.0 percent) and Snow Leopard/10.6 (35.1 percent) have greater shares of Mac OS X web traffic than Mountain Lion/10.8 (26.8 percent)
Mountain Lion/10.8 has increased by 16 percent over the past 7 months to 26.8 percent, but that's still less than 10.6 and 10.7.

With OS X 10.9 expected to be released later this year, the data points to developers having to deal with a more widely distributed Mac OS environment for the foreseeable future. The full report is available on the Chitika Insights website.
The problem is that after 10.9 is released, developers will need to code their applications to work with the "big four" desktop versions of OS X:
10.9 (name TBD)
10.8 (Mountain Lion)
10.7 (Lion)
10.6 (Snow Leopard)
While not as daunting as trying to develop an app for all the flavors of Android hardware on the market, Apple can't afford to lose any developers by making it more difficult to code for the OS X platform.
Apple drops support for older hardware with each OS release, which is part of the reason why many users don't upgrade to the latest version of OS X. (The system requirements for OS X Mountain Lion limit it to Macs with 64-bit GPUs, for example.) But it's unlikely that Apple's going to stop or slow its planned obsolescence cycle.
In addition to adding a lot of new "must-have" features, Apple should consider giving away upgrades to OS X 10.9 for free in order to entice more users to upgrade.

This Is What Happens When You Leave OS Upgrades Up To The OEMs
Oh, wait...
No you had it right
Huh?
Yeah, no PPC will be on there... but that'd be like complaining that I can't load Windows 7 on an ARM tablet.
Intel and PPC, it's more complicated
Most likely it's pricing.
Gouging?
The upgrade price is ~AUD$30 and that allows for the upgrade of up to 5 devices. How can that possibly be "gouging"?
If you really are an Apple user, then you would know that and you wouldn't have made such a blatantly stupid comment!
It's best to ignore the idiots
Sorry, did I hurt your feelings?
Wrong computer!
You should have sold your Mac whilst it was still worth something and bought a PC.
If you have upgraded to a new Mac in that time, then you are a fool for spending even more money on a computer that doesn't work for you.
Says Who?
Virtualization Not Required
most likely is nothing
And I'm not, in any case being "gouged". Every OSX iteration is perfectly capable for my needs, I don't need to upgrade just because there is a new OS in town.
Aging hardware is not compatible with the upgrades....
Exactly
@Jason O'Grady?
Not a bad idea, but the price of OS X is already incredibly cheap - AUD$30 for up to 5 devices. So, would your idea really solve the problem? I wonder if the real problem is the requirement to download the latest OS X versions across the Internet?
many unaccounted for reasons to
Then, OS X versions aren't that different to code for. More or less the same API is available across the board and you can of course check on what version you run and enable version specific features (such as iCloud integration, Facebook and Twitter integration etc minor tweaks) only if you on an OS that supports these.
The rest of the APIs are identical. Which can't be said about most other platforms.
I'm always well behind the times, Jason
Hide the Dock...
Go to the Apple menu...
Go Dock...
Choose Turn Hiding On.
The Dock will only appear when you mouse over it. Otherwise, it's out of sight. :-)
Rosetta.
I was a pain for us for us to migrate some user to newer systems without Rosetta. I wished that Apple would put put Rosetta as in additional install for the newer operating systems so I can upgrade to them.
Upgrade Rosetta, Apple!
Boo. How hard would it be for Apple to get Rosetta to keep on working? Maybe there IS some kind of coding issue at work here, but for now I feel pretty stuck until I decide to open many, many of my older AW files, one at a time, correct and then then save in Pages.
There's never been any explanation other than Apple doesn't support Rosetta anymore. Planned obsolescence indeed! Oh, well...
