Compare that to carrying along a handful of DV tapes. They're cheap, hold a lot, and aren't compressed.
Not compressed? That may depend on how you define "compression". The DV formats I'm aware of do store video in a compressed format--just not a "highly compressed" format. :-) The video data recorded on a DV tape (and uploaded to a computer via firewire) isn't compressed temporally, which is why it works so well for nonlinear editing, but each individual frame *is* compressed with both 4:1:1 chroma subsampling and a DCT. http://en.wikipedia.org/wiki/DV25 Chris
