Apple Will Be Only Supplier of New Dock Connector Adapter
Additional sources have confirmed to iLounge that Apple will be the exclusive initial vendor of a new Dock Connector Adapter, to be sold individually and/or in three-packs. According to sources, the Dock Connector Adapters will sell for approximately $10 each or three for $29, with Apple-branded new USB cables selling for $19 each.According to iLounge's source, Apple predicts it will sell 10 million adapters by the end of 2012, generating $100 million in revenue. It's likely that the adapters would have an extremely high profit margin and while this is a significant amount of money, it is but a drop in the bucket compared to Apple's total sales.
