Your lack of market forecasting experience is obvious. Trying to second guess future sales is very difficult at best. Trying to do it without being able to communicate with potential future customers because of new product secrecy makes it near impossible.
Delivery delays, in retrospect, let us know how well Apple did on their SWAG. I personally think they do an excellent job. Having to wait for 4 or more weeks for a new product is something I can handle.

This product came out of right field. Not an Air, but not a MacBook Pro. It's that transition product as effectively Apple is skating to where the puck will be... Effectively a 'professional laptop' that is effectively not field upgradable. Usually when you skate that far ahead... it takes a while for the puck to come to you... Little did we know that the RD coupled with SSD was the goto product for the high end professional.
Always better to be a month behind in production of a product with no competitor than a month ahead of production of a product with lots of competitors.
