I wanted a speaker for my I Phone, I Pad and Mac.
The latest technology is to use your WiFi to connect to the speaker wireless.
I found a great deal on Klipsch G17 $249.04, full retail is $500

It is supposed to sound better than most systems though the Zeppelin Air does sound better but costs $600.
With regard to Air Play you can utilize the same method with a non-Apple device thought the set-up is not quite as easy. It is better than a Bluetooth method since Bluetooth has compression.
