I use a Dell desktop with a 19" LG monitor for processing all the photos. Its a few years old. I don't use my laptops for processing, but I do have two, a Dell 17" and a real old Dell 15" ( I think it is but could be a 14"). The old one is small, compact and perfect for travel. I bring it to WDW and other places for transferring my photos from the cards to the HD, to my portable external HD and reviewing the JPEG version of my photos. For processing I would look for something with a lot RAM and as large a hard drive as I possibly could afford. When you are looking at HD's, they come in two speeds, 5800 RPM and 7200 RPM. The 7200's are faster but tend to be smaller in capacity so there is a trade off. There is some newer HD technology out there, but it is beyond the reach of my checkbook. I would look for good chip speed. As far as brands, they are like cameras. All the name brands are producing good computers. I have been using Dell's for years and have been very happy, but when I was working I used all different brands. To be honest there was only a "nickels" difference between them.
