I might well be wholly wrong as I can't find any reference to something I read a while back - did I imagine it? Possible. :) I know you're in the storage biz so feel free to correct me as I wouldn't want to unfairly piss on the HDD parade, but as far as I recall the anti-shock technology commonplace on Hitachi/IBM "deathstar" and travelstar HDD which protects the HDD from damage is also a feature on the HDDs in HDD-based camcorders. My understanding is this can cause issues if moving about when recording. I would have thought though that some reasonable sized buffer would allow recording to continue. However given a 30GB disk will support only 7 hours video at highest quality, with MPEG4 and solid state you have similar recording time, but lower vulnerability and (I believe) better battery life. SS tech is starting to make an impact in the notebook world and I think seems the obvious technology to pick for digital video.
