Thanks for the clarification. Yet, since Apple is the only company that has, so far, adapted it, it will remain expensive. Interesting that no other companies (that I am aware of) adapted Firewire 800, which was expensive for some time. Wonder if Thunderbolt will follow the same pattern?
PCs are sold in a commodity market unlike Apple which sells in a quality and performance market. A few cents in cost to manufacture or a few dollars in selling price will make or break a product in the PC market and that market is declining world wide. On the other hand Apple is getting a bit more of that declining market primarily from new purchasers brought into the store by the iPhone and iPad. Because of their experience with the iPhone and iPad those buyers are willing to pay more to get Apple quality and performance and are not shopping primarily on cost. PC manufacturers are all struggling in a declining market environment so they are understandably reluctant to try anything new, especially if it might increase their cost or price.
Apple spends far more on research and development than any one else in the industry. PC manufacturers sit back and wait to see what Apple does that is successful and then only if they can do it cheaply enough they adopt the new technology. Staying on the leading edge is not cheap and Apple greatly prefers to lead not follow.
As I said if you want cheap buy Dell, not Apple.
