13000 units per quarter?
That's it? THAT is what all this fuss is about? 52000 units per year. It's been eight years since the XServe was launched, but let's be generous and assume those figures have held up for the full eight years. We're still talking *total* sales of *less than half a million worldwide*. And I'm being *very* generous with that guesstimate. Presumably there were quite a few upgrades and replacements in those figures over the years, so the actual number of units still in service is likely to be smaller still.
Now... Apple are selling *millions* of high-margin products each quarter. So why the blazes would they give a toss about such a tiny, tiny niche of a market that's contributing mere pennies to their bottom line?
Apple is a *business*, not a fucking charity. If you've made the classical business blunder of placing all your eggs in one basket, that's your own damned problem, not Apple's.
Did you miss the part where Jobs mentioned they'd been running builds of OS X on Intel CPUs *long* before they made the switch? THAT is how you do long-term planning, for Codd's sake! Learn. Please!
Apple are still selling OS X Server. They're still making Mac Pros and Mac Minis, both with server configurations, and both of which are selling in rather larger numbers, so economies of scale can be applied on Apple's part. A Mac Mini will run a small business or production house's email and FTP just fine. A couple of Mac Pros can handle fibre-channel connections and SANs for you if you desire—or you could just buy the kit off the shelf. Final Cut Pro won't give a damn what OS the server's running. It won't even care if it's in a VM.
Yes, you'll need to make some changes to your IT infrastructure. No, it's not the end of the fucking world. Stop acting like you've made a career out of being a victim and grow up. It's not Apple's job to ensure your success. It's *yours*. And nobody else's.
