According to iLounge, a mostly reliable source for Apple rumours, the adaptors that will make the iPhone 5's smaller dock connector work with your 30-pin speakers will cost $US10 a pop, or three for $US29. The future doesn't come cheap!
The pricing, if true — and if there's even a new dock connector in the first place — is in line with the MagSafe 2 Converter Apple sells in Australia for $11.99, which sticks one magnet onto another magnet so that you can charge your current generation MacBook Pro.
Why a three-pack? Because you probably have multiple things that you plug your iPhone into, and it's easier to spend 30 dollars on adaptors than it is to spend hundreds of dollars on new speakers and whatnot. Also, these things are going to be ridiculously easy to lose.
But, hey, all in the name of
profit progress, right? [iLounge]
