But Pod cast implies it should be played on an iPod[/quote:488b49c68e]
Whats wrong with having a word based on a way of using what that word refers to? And why, just because there is a linguistic similarity, are you limited to playing it on another device?
By your logic you should only use your walkman when you are walking, or only use your laptop on your lap? Words derive from a common use, not an exclusive situation relevant to the word stem. To be offended because someone creates a word for a thing that has linguistic similarities to a way of using that thing is a little rich, no?
