2. R2-D2
I wouldnt feel right leaving R2-D2 out. Although yes, once again he is not strictly an accessory and is more of a droid companion, he has some neat gadgets hidden within that small metal shell. He seems to have a gadget for any situation he enters, whether its a small rod that can open electronic doors. This was parodied once again by Family Guy - sorry for the terrible quality... http://www.youtube.com/watch?v=mQtvxzHuxrY Or perhaps the most handy tool was the hidden mini chainsaw which was luckily on the outside of his body which made it easy for him to extend it and cut the ropes and therefore freeing the captives from the Ewoks net. https://www.youtube.com/watch?v=35lvNne21KM I think having your own personal R2-D2 droid to follow you around and help you out with day to day chores would not only make life easier, but more fun. Plus he makes the best sounds. The ever faithful friend.
