hey. Yeah, PR is great. It really does work very well but its different and takes a little patience to learn. As for technical stuff, I'm a CS major and addicted to coding and use it for my textbooks. You can use it on any type of material. It helps a lot for tech stuff because since you learn the material in layers you remember much more of it and more of the details. Photoreading is superior to other reading systems is almost every way (cant think of what the almost would be but i'm sure there is one).
