Well i have worked for apple up till now and a few things that i have learned about them seem kinda interesting. First i found out that almost all, if not all, apple DEMO models out there come with different hardware then most consumer models. That is one reason why apple doesn't actually want stores selling demo models that often unless they give special permission. In these DEMO models that apple displays are better optical drives that can read and write at faster speed and are known to be more reliable then the consumer model drives. I have looked at a lot of apple laptops and desktops (iMacs and MacPros) and found this to be true. Also another thing is that the iPad DEMO models allow you to revert back to older firmware then consumer models and that's why apple wouldn't let us sell them to the public. No apple didnt tell me that but when trying to jailbreak the DEMO iPad i upgraded past the current accepted form of jail breaking firmware. So i thought i would try to go backwards and what do you know the apple server verified it and let me install that firmware. So i guess we know that there are models out there that do allow people to go backwards and man o man wouldn't jail breakers like Green Poison love to get their hands on an iPad like that. HAHA so if anyone else has good info please post it here.
