This new iPod shuffle just goes to show that Apple do listen to their customers. We wanted buttons and no gimmicky propriety headphones, and they finally listened! This new generation shuffle adopts a similar design to it's older brother and let me tell you, this thing is TINY. When I got the box I was astounded at how small this thing actually is. I got the silver one and it's shinier than in the photos (very nice finish to it). I can imagine this would be easy to lose but as long as you have headphones plugged in you shouldn't lose track of it too quickly. It's an absolutely gorgeous little device and will look good clipped on any bag, shirt or trouser pocket.
Otherwise, it contains the same features as before. Voiceover helps you choose playlists, check battery (very handy) and also tells you the song that's playing. Battery life is stated for around 12 hours, but as with most Apple estimates you should half this to get a more realistic figure. No pin connector like the nano/touch/classic as usual, still amazed at how they can get data transfer through the headphone jack! For the exercise fanatics (possibly the shuffles main customer base) I can't really tell you how it fares, but at least with the buttons you won't have issues with the remote this time.
All in all a fantastic mp3 player at a great price. For £40 you get a music player, no more no less. At least if you do manage to lose it, you haven't lost an expensive investment!
EDIT: Had the device for a week now. Charged it last friday and it's only just dropped to 75% after an hours play every day. The small light also changes colour depending on battery strength: Green for good charge, orange for less than half and red for 25%.
