Almost forgot to give an update on this.

The Jawbone Jambox was very well received. Evidently he was looking at it in the Apple store when I got my MacBook Air (of course I didn't notice).

Anyway, for something so small, the sound is rather incredible. Worked without any issues from 2 different iPhones, an iPad, and a MacBook Air (I had never used Bluetooth from the MBA before).
We played around with using it as a speakerphone for the iPhone, and it worked well for that too. But it really is great for sound from any of the devices we've tried so far.
