Decent enough, but...
...proprietary cable connectors is something that seriously needs discouraging.
You see I have a dream - how nice would it be to just reach into your box-o-cables and pull out any old mini-USB cable to charge and xfer music with ANY device.
I indeed have a few devices like that, and I will now avoid any such device with proprietary cables as its just likely to go missing and render the unit non-updateable, and possibly, unchargeable!
Your typical suitable resolve to this problem would be a removable memory card. Just whip the card out into your '5-million in 1 card reader', but . . . oh . . . this unit doesn't have that option either.
Either than that, this device does not stand out above the crowd, especially with its usage difficulties as described.
Boo hiss to Samsung.
