I am shopping for a laptop that can be used for camcorder video

Tape based video would ease the requirements on a computer. This is an
option.

The best brands would be HP.
Sony had some quality control and explosion problems about a year
ago.
A Sony desktop will work well for years.
Toshiba is good.
If Dell would be good, what specs should Dell be given?

What amount of storage would be necessary 100-200gb?

If more power is necessary, wouldn't this be in RAM. If more ram is
needed, how much more and which laptop seem to do the job.

Is a graphics card necessary for video editing? Are there any special
or preferable requirements here?

Are there any features that should be included that I missed?

any help appreciated
