Apple has ditched their 'clip' design and gone back to the original ipod shuffle 'tall and thin' design! They've removed any buttons from the actual device and instead put them onto the earphones...

I'm on the fence with this one. I like the idea of controlling it by the headphones, but I think the beauty of the ipod shuffle was it was good for people like my Mum who can't get their head round a click wheel and just wanted a high quality *simple* iPod, and I just don't think she'd be able to use those new earphones
