HD camcorders are not new, they've been around for a while now. Not sure about your requirements, but any high end point and shoot camera has the movie mode as well along with HDMI outputs (HD that is). An example of this kind of the camera would be Canon Powershot G11.
Also if you can get a Eye-Wi PRO wireless card, life would be a lot more easier, then you could keep taking movies and pics and the SD card wirelessly sends all movies and images to your computer and a website of your choice. This means that you don't have to worry about the manual step of transferring images back to computer, housekeeping etc.,
I never hear my wifey yell
"Did you upload the photos to computer or not?" anymore
