All three accessories lose their reliance on disposable batteries, instead moving to internal rechargeable lithium ion batteries. Like iPhones and iPads, they're rechargeable via a Lightning cable. A full charge should last a month or more, according to Apple.
The rechargeable battery allows the trackpad to slim down, removing the bulbous battery compartments that dominated the previous designs.
The new Magic Keyboard and Magic Mouse 2 are default accessories with all new iMacs as of today, and you can swap in the Magic Trackpad 2 for an additional $40 when ordering.
The accessories are all available separately, too -- and they'll work with any existing Mac that utilizes Bluetooth 4.0 or better wireless.
But they're all a bit pricier: $79 for the Magic Mouse 2, $99 for the Magic Keyboard and $129 for the Magic Trackpad 2. That's an increase of $10, $30 and $60 over the prices for the respective predecessor products.
