The new iPod Shuffle is 7g lighter (down from 22g to 15g) and half as long (down from 84mm to 21mm). But it’s wider and deeper by 2mm (up from 25mm to 27mm and 8mm to 10mm respectively). Plus the clip.
Then there’s the memory stick factor – there’s no indication the new one can be used as a memory stick and anyway, it needs a dock to function.
I’m really not sure. Should I pop down to Dixons before they sell out of the old kind?
