So, I am the owner of aniPod Shuffle. I have it for more than one month so I guess now I can express an informed my opinions about it.
The device is great because of its size (very light) and the its autonomy (plays 10+ hours of music when fully charged).
It came with just a few instructions (not the complicated instructions that you would expect to find when you get a device like this - gotta love the simplicity of this approach) on how to operate it and the most important thing in the instructions was the link to download iTunes. Now, iTunes is not the sharpest tool in the shed (it plain dumb in some aspects) but it gets the job done.
As a downside, the device only charges through USB (at least that’s the only charger included) and the cable to charge the device couldn’t have been shorter (it’s literally just a couple of inches long making charging the device on anything else than a laptop a very nasty task).
One might also consider the controls placed on the earphones cable to be inconvenient, but I am willing to accept them there for the sake of the small size of the device.
Overall I like the device a lot and think that I am turning into an Apple fanboi :)
