Surely anyone wise enough to know better can see through the marketing speak. There's a
different to genuine listed improvements and the "generation 2 audio" thing which is
really just a non-technical way of saying the new product is better - as most proespective
users at this level probably wouldn't want to read frequency response charts and
distortion figures.
Anyone who doesn't know better has a learning curve to go
through...

"Please buy our new product! It's exactly the same as the old, it
just looks newer!".
Dilbert comes to mind, here...
