Hey I'm a September Layoff casualty - so I know about the money problem - belive me, I'm right there with you!
It sounds like you would be doing a lot of both - Digital Pictures and Video, and I take it you can only get one or the other. So it's kind of a toss-up there.
Personally - I'd go for the DV Cam.
Like testuser said, DV Cams are not the best still picture takers, and Digital Cameras are not very good at recording video.
But I think Digital Cameras are worse at recording Video (less ram, slower chips, etc.) than DV Cams are at taking pictures (I strongly recommend capturing frames rather than using the "Photo" feature on them - but test both see what you like).
And if you're filming a lot of action video like skateboarding - you want something that will keep up with you. That's where I think the DVCam wins (but then again - I have a $150 Digital Camera - I have no experience with $400 ones)
10 Gig hard drive might prove to be too small - but take it easy at first and delete whatever clips you don't want to keep to save on drive space. You might even want to output the finished product back on the DV tape (I was pretty blown away by that feature myself <smile>) so you won't quickly fill up your hard drive (until you can buy an external kit or something at least).
I don't know where you live, but out here in Burbank California - there's a store called Fry's Electronics that has that drive I spoke of. Wish I had the money to get it (or two, or three?).
Hope that helps, and good luck!
