A convenient accessory for use when viewing videos. The dock includes a 3.5 jack socket at the rear for plugging in a pair of speakers: great for listening to music (Samsung advise not to use this socket for headphones but to use the one on the tablet itself). The larger socket on the rear of the unit lets you connect to a PC for transferring files and to update the firmware. This socket also connects to the charger, which can be left in place while using the tablet. I would have awarded more stars for build quality alone, but it is not an essential accessory; a tablet is intended mainly to be held in the hands in normal use. Spend your money first on a good protective case or cover, and buy the dock as your second accessory.
