The first AirPlay speaker system announced, way back in the fall of 2010, iHome's iW1 ($300) is finally available. (We've got a review in the works.) The iW1 includes a built-in battery for portable use, and a handy iOS app makes it easy to get the iW1 connected to your wireless network: Just connect your iPhone or iPad to the iW1 using a USB cable, launch the app, and use the app to choose your Wi-Fi network. The iW1 also works with a slew of iHome iOS apps for configuration, Internet radio, and alarm functions, and buttons on the iW1 itself let you control playback, whether the music is coming from your iPhone, iPad, or Mac.
Although the iW1 doesn't have a traditional iPhone dock cradle, you can use a USB cable to connect your iPhone, iPad, or iPod to the system for direct music playback.
