Slight iPad Shipping Delay Due to Software, Not Hardware?

Daring Fireball's John Gruber claims to have heard from his sources that the slight shipping delay (about a week in the U.S. and on the order of a month in the first batch of international markets) for the Wi-Fi iPad is due not to hardware production issues but to Apple putting the final touches on the software for the device.It was the software, not the hardware, that took a week or two longer to finish than they'd hoped. Nothing extraordinary or unusual, just the usual hard-to-predict timing of turning software that's almost ready to ship into software that's ready to ship. In the grand history of major OS release date slips, one week is pretty tame.

A report early this week indicated that a "manufacturing bottleneck" would be responsible for limited iPad quantities at launch and possibly a delay of the entire launch. Another analyst claim yesterday offered similar information, but noted that the issues were not related to "glass or manufacturing process". If Gruber's sources are correct and the delays were simply due to software, Apple should be able to quickly deploy the final software version to units in production and rapidly fill its sales channels for launch.
