The Lightning connection

The most noticeable changes to the iPhone 5 is its size: The phone got taller and thinner, and the dock connector got smaller.

To make the device as slim as it is, Apple had to do away with the 30-pin connector that it has been using since 2003.

That may make sense, but in one industrial-redesign swoop, Apple rendered millions of iGizmo accessories useless for those who upgrade to the new iPhone.

There is an adapter available, but that comes with more bad news: It'll cost you at least $29 a pop, and the adapter doesn't support every feature of the old connector.
