Any notebook with a firewall port can do video editing.

However, the Sony notebooks are optimized for using their Sony camcorder products and Sony memory stick cards. If you have a Sony camcorder that was their intention (to get you to buy all Sony products).

Apples are outstanding for video editing if you get a model high enough that has everything you need. The Apple Powerbooks are over $2000 but they have a 17" LCD model that weighs only 6.9 pounds (Steve Jobs used that in the hospital while having pancreatic cancer surgery). A similar PC notebook would be 9 pounds or over.

My Compaq X1000 series Centrino Pentium M notebook is 6.5 pounds with a 15.4" widescreen.

If you really have a group of friends with Apples that may be the way to go for you.

Otherwise, you can get a great Pentium M centrino notebook with a 15.4" widescreen like the Toshiba M35 series or the HPZT3000 series or Compaq X1000 series (same notebook -- different cases) -- but make sure you get firewire, dedicated video (not shared or integrated) and choose your LCD size and weight carefully.
