I am looking into getting a digital camera but am stumped by the different memory sticks, flash cards, secure multi media, xd cards etc. that there are for different cameras. Is one better than another? also I am seeing card readers- which seems like a good idea - what does 8 in 1 or 6 in 1 mean? So far all I have seen are ones that say USB connection, nothing about firewire. Could anyone shed a little light on this subject for me? I have posted in a few forums but haven' t gotten any response as of yet. Thanks a bunch.
