For business users, the tablet should offer access to supersized versions of iPhone applications, which could drive corporate acceptance of both devices.
iPhone 4.0 software, expected to be introduced as part of the tablet package, will offer developers some new options for creating apps that work equally well on both the small (iPhone) and large (tablet) screens
iPhone 4.0 as a "catch-up" release. This is what has me excited about the event, iPhone 4.0 and perhaps the 2010 versions of the iLife and iWork applications suites, should they appear.
Key among these is multitasking, which is the ability to have multiple applications running at the same time.
