Apple isn’t always so forthcoming with certain product announcements. I guess it’s their version of an Easter Egg? Like the Mac Pro update and death of the 17-inch MacBook Pro, they also updated the Airport Express Base Station.
It looks a lot like the Apple TV but it’s white and no longer requires you to plug it directly into the wall. The new Express Base Station supports simultaneous dual-band 802.11n and AirPlay all for $99. Maybe I’m missing something but it appears that this is just a cosmetic change with the addition of another ethernet port.
