Hi, I'm going to be buying a new Powermac in the next week and am not sure whether to purchase the 20 inch screen or 23 inch screen. I do a reasonable amount of video editing, but only DV. I am not sure which to choose. I know the 23 inch is fully HD which really appeals to me as it is very future proof like that. At the moment I am working on a 12 inch powerbook and it is really starting to annoy me, any screen is a step up, but I'd be really pleased with some recommendations. Thanks a lot.
