Recently, many have been saying that 8gb is to small for HD recording. However, according to an "Apple expert," 1 hour of 720p 30 frames/sec equates to about 1 gb of storage usage. I use the term loosely because, as we have seen in other post, their merits do not always correlate to their title. Unfortunately, I asked the Apple rep. Carla G if I could post the chat transcript online, and she told me that no copy of the transcript could be published online. However, if there is any doubts, feel free to contact them.
