I got an iPod Touch for Christmas this year and it is awesome! I tried it with our Internet Remote Amateur Radio Station and I was amazed at the audio quality. Definitely communication grade audio. I'm able to operate HF/VHF/UHF with a small device from anywhere in the world that has WIFI. I have done this before using my HTC Touch Pro but the iPod Touch is so much easier to use for remote operation that I'll likely never go back. Until then here is a quick video of the iPod Touch tuned to WWV.
