So Ultimate isn't eligible for extended (PAID) support? So what? Would the average Vista Ultimate user actually spend the tens of thousands of dollars for Microsoft to write custom hotfixes for an older operating system?

Chances are, anyone who buys Vista Ultimate is a power user and/or enthusiast and they will upgrade to the next OS by 2012...
Now, if you're a large business and have 10,000 copies of Vista Business deployed, and you encounter a show-stopping bug in your desktop OS, you will gladly pay $10k+ to have Microsoft address your issue and write a hotfix for you.

If I have 10,000 copies of a MS product I already paid my dues, and MS better get off their ass and fix this shit NOW.
That would be my attitude if I was in situation you describe.

Makes sense actually. But gives too many varient OS's in my opinion.
