Yes, we don’t have the luxury of spending a lot of time creating/developing our projects.
Would you say that most films that are recorded using flash memory are grainy, or would it depend on pixels, HD, quality of cam, etc.?
The Flip MinoHD and Kodak Zi6 will do 720p, so should look decent on any digital TV. Kodak has an SD slot, so if you want to record soccer/football/basketball games, that might be a better choice. Kodak is a little bigger overall, but also has bigger viewing screen and replaceable batteries. The Flip is more of a go anywhere camera.
In addition to the CCD/Pixel count, there's also the processor and its associated software(firmware). All that is related to camera quality, with the higher end models costing more. HD is HD because it records more detail, and more detail requires more storage. Seems to me that miniDVD is going to be limited compared to what you can get in flash cards these days, and flash also has the advantage of being smaller. Internal HDD's are susceptible to shock and being internal you'll be required to transfer to computer before freeing up space for your next project, whereas cards or other portable media can be swapped out for different subjects or scenes as needs dictate.
