OOps, I meant 'Build To Order vs Standard Spec'.... Here's a question that someone may know the answer to... How are iMacs produced in the factory? Do they: 1, come off the production line in only the standard specifications (as defined on the Apple web site), then retrofitted with BTO options or 2, they produced in all possible variations (negating the need for retrofitting) I would prefer #2, my iMac order would be chosen off the shelf, matching my BTO order, whereby there is a rack of iMacs with all variations of screen, processor, hard disk etc. #1 could in theory be open to possible damage if, say an order is placed on the apple store, chooses a 2.4GHz based iMac then selects a 2.8GHz upgrade and a larger hard disk. If the production process is taken literally to 'upgrade a standard 2.4GHz machine', it could mean an off the shelf standard 2.4GHz iMac is opened up to perform the user selectable upgrades by an underpaid factory worker... Could this have any truth in it? It would certainly make sense from a production speed perspective to have all iMacs build to a set spec and then retrofitted afterwards for those BTO options (option 1) - but this would depend on the percentage of BTO orders that arrive. If it is very common for people to have varying specs, then option 2 would be favorable for apple.
