For those who are tempted and going for it, yes, it is a good deal! The 3rd generation has a beefier speaker (1.6" instead of 1.1" in the previous generation), because of this it has apparently much better sound quality and if you have two of them you can connect it in pairs for stereo sound!
I have one which is the previous version (2nd generation) I am happy the way it is, does what it is supposed to do but I would not be tempted to upgrade to the 3rd generation for the simple reason I never used it for listening to music. I have plenty of other equipment to keep me entertained
