I am looking at getting some extra bits to go with my tablet when it arrives next week 1) Spare USB charger cable - can use USB charger in the car. 2) Protective case 3) Spare memory cards -so I can pre load movies/ music. 4) External Keyboard. - have been offered a second hand bluetooth unit that was used on a PS3, don't know if it will work? 5) Cable to connect to my IPOD dock(for the external speakers) has a 3.5mm phone jack.Also have an adaptor to run my decent(cheap) headphones[honest they are cheap ones-Grado SR80] if I wanted to watch a movie in bed using the seperate headphone amp I have. Is there anything else I may have missed?
