Aside from the big updates to the iMac, Mac mini, and MacBook, Apple also released a new AirPort Extreme, Time Capsule, and Apple Remote.
The new AirPort Extreme and Time Capsule feature multiple-input multiple-output (MIMO) which, along with improvements to the antenna, give up to 50% better Wi-Fi performance and up to 25% increased range than with the previous-generation products.
The Apple Remote has received a big makeover. The remote works just like the previous one did but now has the same silver and black color scheme as the iMac and MacBook Pro does. The play/pause button has also moved below the selection buttons (an odd choice if you ask me)
