What crossover? You do realize the for the apps and the files they create too be useful on a variety of hardware the apps have to be similarly feature full. The whole wide there is to have nearly the same features on both platforms and the web.Is this the beginning of iOSX?
We're getting more crossover and while Apple insists on a separate OS for each form factor, I wonder if they will eventually get to the point where the user interface can suit both.
