Apple debuted its first TV ads for the iPad during the Academy Awards television broadcast on Sunday, doing what Apple does best: showing us dozens of things we can do with an iPad in just a few seconds, all to the tune of some hip music we’ve never really listened to before. Yet these ads are like walking into a restaurant where the menu doesn’t arrive — we’re hungry and salivating, but in this case, the key that holds the fine-print details won’t arrive until April 3. In just 30 seconds, Apple showed off all the core features of an iPad.
