Order Placed: Plugable USB 2.0 7-Port Hub with 15W Power Adapter

With my MacBook Air as my primary computer, I quickly ran out of USB ports for all of my peripherals.

The Plugable USB 2.0 7-Port Hub with 15W Power Adapter (~$18, Amazon.com) has enough ports for all of my devices, and external power makes sure that they all stay on.
