I create videos with both a Mac and a PC. They serve different purposes for me, but eventually I plan all my activities to move video on the Mac
Currently I use my MacBook when I want to put together a short video that is shot with a webcam.
MacBook makes it easy, because the webcam is built in. The computer comes with basic video editing software called iMovie.
If I want to capture video when I travel, I take my Casio Exilim ZoomEX-Z850. I love this digital camera - Features: 8.1 megapixels, 3x optical zoom, 8x digital zoom, and really small, but with a 2.5 "LCD screen In short, it packs a lot of power in a smaller package..
In addition to the camera, I'd suggest picking up a tripod. Just a little 'to put on a table is good - you can usually a tomb for $ 20 or less.
And take some extra memory cards. And 'where your videos and images stored with the camera. I would suggest always to 2 GBMemory Cards. They fit about an hour of video and tons of pictures.
You can also create a camera to your videos. If you use this method, you need to get a FireWire cable to connect your camcorder to your computer.
Any direction you go, you can have fun on the Stock Exchange of online video.
If you do not have a camera yet to find a price comparison search for the best deals.
