"Excellent Product Does more than expected"4.5 starson by bartman1
Pros: Can be Base Station and Air Tunes port simultaneously
Cons: Apple doesn't document all features (probably to protect higher-priced Airport Extreme Base Station)
Summary: Plugged in to router. Started up iBook and configured. No CD necessary - software included with OS X 10.3. Other computers on router can use unit for iTunes with no configuration. Airport Express also functions as base station for wireless network.
I assume Apple doesn't fully describe the capability of this unit because it is so good it would cut into Airport Extreme Base Station sales which is much more expensive.
This is one of the most significant examples of Apple's design brilliance; even people like me who are confirmed Mac users are amazed at their creativity and innovation.
