Now we know the true meaning of “Back to the Mac” (the name of today’s ). It didn’t mean a return to an emphasis on the Mac. Rather, it meant a looping back of features from iOS (which is based on Mac OS X) to the Mac itself. All those who predicted that the next version of Mac OS X would somehow incorporate features from iOS were right — if not always in the details.

I, for example, that Apple would put iOS features into a revised version of Front Row. While I missed the bull’s-eye here, the new Launchpad and MissionControl features come close to what I was imagining. Of all the iOS features migrating to Mac OS X, there is one that looms above the rest — the Mac App Store.

That’s right, for better or worse, you’ll now be able to purchase Mac software from an App Store, just as you now do on your iPhone. Secure e-mail for a mac app free. Although announced as a new feature of (coming this summer), Apple considered it to be such a big deal that they are making it available for Snow Leopard in only 90 days.

Developers can start submitting apps to the Store next month and start learning about it (on Apple’s Developer site) today. We’ll all be learning much more about this new App Store in the days ahead. Which is good. Because what Apple showed us today amounts to little more than a tease. There remain numerous as-yet unanswered questions, from the mundane to the philosophical. For some of them, I can take a good stab at the answer. For others, my crystal ball remains cloudy.

Will Mac users be required to use the App Store to get software? This is an easy one. It was answered definitively during the Keynote. The answer isno. You’ll still be able to download software from the Web or install it from a disc — and run it from the Finder. While there was Web chatter fretting about whether Apple might introduce a required App StoreI never took this seriously. Apple would not risk such a dramaticand certainly unwelcomechange.

At least not yet. I am quite certain that if Steve Jobs thought a required App Store would be greeted with unanimous applause, we’d be seeing it tomorrow. It may yet come to passafter we’ve all had a few years to get comfortable with the idea. But that’s a concern for another day.

This doesn’t mean the App Store’s immediate influence will be minimal. Assuming the App Store is a success (which seems likely), developers may soon feel compelled to sell the programs via the Store — because non-Store sales will have fallen off a cliff. Before too long, the user’s option to purchase software not in the Mac App Store could be sharply curtailed. Will software sold via the App Store be available only from the App Store? This seems likely — although not certain. At least for Apple software, it would make sense for Apple to limit sales to their own App Store. What better way to promote the Store’s use?

This means you would no longer be able to go to a retail Apple Store and buy a copy of iWork. You’d have to get it from the App Store instead, just as you now have to do with all iOS software.

Third-party software may be able to swing both ways. But as Apple is taking a 30% cut of all software sold from the Store, does it really want developers to compete with that by selling the software outside of the Store as well?
