Question: Videocasting / Vodcasting With Mobile or Camcorder?

We will soon get into vodcasting / video blogging. I am looking at using either a decent mobile camera with video capabilities like the Samsung U600 or using a digital camcorder. What tools would you recommend for a good quality video casting / video blogging?

I am looking for good quality video & audio which can be easily & quickly processed on my Linux environment for uploading.

Update: I have decided to go for a low end phone and additionally purchase a DVD camcorder for my video requirements. I can get better video quality for equivalent price.
