The iPad's slightly delayed April 3rd release may actually be the result of time spent refining the software if a rumor proves substantive. Historically accurate with other leaks, John Gruber claims that Canaccord Adams' beliefs in a hardware issue are mistaken and that the actual problem was simply polishing iPhone 3.2 and companion apps in time for a release. The roughly week-long gap was simply a virtue of the "hard-to-predict timing" that comes from turning a beta into a polished product, Gruber's source said.
