- The new Lightning connector is easier to insert and remove, even in the dark, since it doesn't matter which way the connector is inserted (up or down). With the previous Dock connector or USB micro connectors (e.g. Android), you need to check to make sure the cable facing the right way before inserting.
- While it's too early to tell, my impression in that the new cable will be more durable than the previous Apple Dock 30-pin connector. I have several Dock connectors where the larger plastic end broke off or cracked.
Lighting connectors are more expensive than the prior Dock connectors but third party cables have just started to hit the market at lower price points. While it's unfortunate that older accessories won't work without an adapter, this is a short-term problem. Apple introduced the first 30-pin Dock connector with the release of the first iPod over 10 years ago. I'm glad to see that Apple is innovating and moving the ball.
