Due to “unforeseen issues”, Apple has had to push back orders on its new entry-level NVIDIA-based MacBook Airs. The company sent out an email to pre-orders explaining that it will be unlikely the systems will be delivered before the Thanksgiving holiday, as previously promised.

The delays seem to only affect 1.6GHz models with 120GB SATA drives, while the 1.8GHz models arrived earlier than anticipated. Sources believe the delay is a direct result of component supply issues with the 120GB SATA hard drives.

Apple fanatics should keep in mind that the early bird doesn’t always get the worm, even if it is delivered with free shipping.
