Apple switched from its 30-pin connector to Lightning port with the iPhone 5 in 2012. Eventually it added a $29 dock for that device and now has a more expensive one to accommodate the larger iPhone 6 and 6 Plus.
While the new 15-inch MacBook Pro with Force Touch trackpad and updated 5k Retina iMac are in the spotlight today, Apple quietly added an iPhone 6, 6 Plus Lightning Dock to its store as well on Tuesday. Priced at $39, the new dock costs $10 more than the the older model.
You won't get any additional features for that additional expense though. The only change here is the broader base to handle larger iPhones. And you won't get a USB cable with the dock; you'll have to use the one that came with your iOS device.
I opted to buy a Belkin charger and sync dock months ago from Amazon for less than half the cost. It didn't include a cable either but that's actually a benefit to that product's design: You can use either a 30-pin or a Lightning cable with it since you feed your own cable through it. It also has a headphone jack that fits into an iPhone or iPod touch for audio output.
