It can run iPhoto, Garage Band, iMovie, Pages, Numbers, Keynote, Omnifocus, iThoughts, and thousands of other extremely well done tablet apps that Android can't.
And incidentally that's probably the single most important thing to most tablet owners.
Oh I see how you would like to classify what the tablet can and can't to. I disagree with your criteria though. IE - Both tablets can do word processing, slideshows, edit videos, have music creation apps, photo editing. Would you say the PC can't do what a Mac can do and define that by saying that since Final Cut Pro isn't on a PC that it can't do video editing?
Yup.
What Devs Say About iPad (but not Android tablets)
http://gigaom.com/mobile/what-devs-say-about-ipad-but-not-android-tablets/
"Even now, however, Android tablet apps are taking a backseat to those for the iPad. Its very rare that an app first appears on Android devices over those running iOS. And that gives Apple a competitive advantage in this market: Consumers in the know wont want to invest in the devices that get software titles second (if at all), but will buy the hardware that has the best supporting software and ecosystem. If you dont believe that, just ask a mobile app developer."
Meaningless link is meaningless link.
