It’s not so much that the camera (not yet purchased) doesn’t have external media, it’s anticipating a need to shoot hours and hours of stuff and preferring the cost-per-gig of HDD over that of flash media.
(Not for me, either, as it happens.)
Current suggestion is a laptop and 2TB external HDD with daily transfers off the flash media. This seems like a lot of hardware to carry around, through airports, etc - and expensive hardware to leave in hotels, yadda-yadda.
Looking at Quickstream and Firestore, which allow just this functionality - but the price tag doesn’t really begin to make sense if part of the aim is to economize on storage media. I am so far out of this market, I am actually surprised that this isn’t a commonly offered feature. You’d think it wouldn’t take much to allow export of raw DV, even to a USB drive.
