I know I have used a small drive to move photos from my work iPad to my work Windows laptop. However, my knowledge is strictly limited to my exact usage because I've never done anything else with it. My friend is asking if she could copy a video from her iMac onto a drive of some sort, and then plug that in to the iPad and access the video (this would be a video she would've taken with a camera, and edited on the Mac). Her ability to do this is what will determine whether or not she buys an iPad (she currently hauls her iMac with her to various places, which is DARN inconvenient). Anyway, is this possible, and, if so, will any hard drive work, or are there ones specifically suited to the iPad?
