The iPad is a bit of tragedy. If it was an open platform, a lot of its problems would be solved - first by third-party software, and later perhaps by Apple copying those successful features/solutions. Because the iPad is a walled garden, it's at the mercy of Apple's narrow vision for how it can be used.
