I believe you can also get a wireless internet portable radio too with 700+ channels.
It's a lot more than that. I've got of them, one of each make - though they obviously use the same OS and are virtually identical. I prefer the tuning knob on the Acoustic Energy model rather than the flat spin disk on the Magic Box.
I have in the bedroom and one in the kitchen. Allows me to listen to R4 in LA, Paris etc. Only disappointment is that on R5 and other channels they broadcast an announcement or other material when football/Grand Prix etc is on, as they don't have worldwide rights.

They have other models such as tuners that plug into an existing HiFi etc.
