Oh, another "cool" thing you can do a with a PDA and media, is to have the PC with all your MP3's accessible from the internet (well, at least the necessary ports). While out in public in a hot spot, you'll be able to grab MP3's from home. I do this all the time while traveling. As previously noted, streaming audio over-the-air isn't very practical on battery power but downloading (whatever transfer protocol you prefer) them completely for playback works fairly well. I just enable the wireless, grab what I want from home, disable the wireless, begin playback of the files, and then turn off the PDA's screen. Not only do I do this with MP3's, but also Audible "books" from home. Playback with the screen off lasts for a few hours on battery power. Usually driving while listening to "books", so using a car cigarette lighter power adapter though.
