You're not going to find specific models of laptop computers for video editing. Laptops are not designed for the sole purpose of providing the best video editing experience. What you need to do is look at specific laptop features and components to determine whether a given laptop model is capable of meeting your video editing requirements. Processor, hard drive, memory, video card, and display size are all important factors to consider in choosing a laptop to complete your video editing work. If video editing is your job or something you spend a lot of time on, then I don't think you're going to get away with spending under $900 on a laptop computer for video editing. You can however seek out the best laptop deals possible that include the necessary components for efficient and quality video editing.
I recommend the following minimum system requirements on laptop computers for video editing: dual-core processor, 2 GB DDR2 memory, 160 GB hard drive, discrete video card, and 17 inch widescreen
