However, it does leave out some of the downside in terms of Apple's plans and achievements in the area of Office productivity apps.
For instance there is no mention of the fact that the iPad apps are still feature incomplete relative to the desktop versions of iWork, ....
You use iWork daily, observe some flaws, and call it a placeholder Apple doesn't care about.
Want to expereience a real placeholder the vendor doesn't care about? Try Microsoft's Windows version of iMovie. Or try using Office for Mac. Completely ridiculous. iWork has some flaws, and the iOS apps are not (nor do they claim) feature parity, but they are usable as you noted yourself.
The fact is that Apple has put its iWork efforts into iOS in a very short time, and is set to release iCloud versions of its iOS iWork apps soon. After that, I'd expect a new set of iWorks apps with some additional Lion refinements (although a new rev, albeit free, has shipped).
Compare the editing capabilities of iWork iOS/Mac against other versions of "mobile" office apps from Microsoft and others, and I think you'll be forced to agree that Apple currently makes the best mobile suite around.
The fact that Microsoft really doesn't have a functional mobile suite (or a real tablet platform to deploy them on) is kind of the point of the article I think. I mean really, Microsoft has a monopoly on both Windows and Office and is just letting Apple step on the their face in the mobile market, which is where growth is happening.
This is really incredible. Even more incredible is that AI is the only source to recognize this. Wait a year and everyone will catch up to what DED is saying today.
