Apple silently updates AirPort Express

Updated. Coming in stealthily under the din of our WWDC coverage, Apple(s AAPL) today has updated its AirPort Express wireless router.
The new model doesn’t plug into the wall like the old one. Instead, it looks just like an Apple TV, and even has the exact same dimensions, but comes in white instead of the Apple TV’s black. The back of the device features two Ethernet ports (one WAN, one LAN), a USB port and an analog/optical audio jack for speakers.
Among the new features of the device are support for simultaneous dual-band 802.11n, which means you can use both the 2.4GHz wireless band and the faster 5GHz band at the same time. AirTunes has been replaced with AirPlay, so you can send songs to an AirPort Express from your iPhone or iPad as well as your Mac. Also, if you have more than one AirPort Express connected to speakers, music can be played on all of them at the same time, which is pretty neat. (Update: Sorry, playing music on multiple speakers at once isn’t a new feature, as pointed out by a commenter. Sending songs to an AirPort from an iPhone or iPad also isn’t new, but is only supported on last-generation models that have 802.11n.)
The new AirPort Express is available now for $100. Now we’re left wondering when the AirPort Extreme and Time Capsule will get updates, or if they’ve gone the way of the 17-inch MacBook Pro.
