I have 4 - 2 11g, then when the 11n's came out, I couldn't resist and bought 2 more.

What's so fantastic about them is the wide range of functionality:

1) Can feed speakers, picking up wifi streaming from one or more Macs (and PC's too, anything that runs iTunes).

2) Can network a USB printer, turning it into a wifi printer on your network

3) Can be a wifi base station: plug an ethernet cable into it, and it provides wifi access. Great when traveling: you can access the hotel wired network from anywhere in your room.

And all from a funny little gadget that looks like a strange power plug :-)

I don't think Apple sells them hard enuff.

David
