I talked to Mary Tawfall, one of the tech advisors, and she told me that all that is really required is a fast enough processor, decent amount RAM, and large enough hard drive space (for saving a lot of images). She even said that most new laptops off the shelf should be fine. They also would like a 4 year warranty, but I think even that is up to us.
I asked specifically about the expansion slots and she said not to worry about those. But she did say that XP Professional is required and that if you come loaded with the home edition they will make you upgrade it.
