So, let me get this straight, the author prefers using a USB cable to sync then the wireless also provided? Once again, all app developers should know not to use the private APIs (although, to be fair, some have got caught based on using a framework from a third party). Since the new iPad looks to have some sort of common file area and sync support for that, I think I see why those calls remain private and Apple is looking at them.
The rest of the article is stuff that would be good on the AMB podcast.
