thanks @trewyn15
* re iPad - with the connector would the IOS software still act like a normal PC that could see a USB drive attached (i.e. after the gopro is connected) & allow you to transfer files from it to the iPad somehow?
* re card readers - I'll have a look, do they typically come with storage attached? i.e. like a storage device with a slot for an SD card is this what you mean? how do you tell the device which files you want
for the iPad it just allows you to upload and then delete the files from the card so then all the files are saved on the iPad and then your card is empty, I haven't had experience first hand with it but from what I have heard and seen it works great. For this one to work you actually have to take the memory card out and put it into the iPad attachment, check it out here:

He also uses a USB SD Card reader in the video, which is what you could use alone if you were to upload the pictures and videos to the computer. Also, in some of the recommended videos, it looks like you may be able to use the GoPro USB cable to upload the pictures, although I'm not sure how that would work with a GoPro, I haven't gotten to play with mine too much yet.
Hope this kind of helps you out as far as those two things go.
I would also like to hear of something that you can use just to go from SD Card to a thumb drive or external hard drive, unfortunately I think that because an external and thumb drive both need power to operate, there may not be something on the market for them.
BTW, do you have the HD Hero or HD Hero 2? I have the 960p HD Hero and love it!
