Finally, an IT book for the rest of us. Walters is lucid, concise, engaging, informative, and funny, and manages to do so without insulting your intelligence. He lays out the contours of the development of the computer industry, its successes, its failures, and why, and most importantly, what that means for the the computer systems and software that are available in the market. For me, computer literate, but no computer engineer, the Essential Guide to Comuting helped me determine what kind of computer configuration (memory, chip speed, graphic card, video card, etc.,)best met my needs. I highly recommend EGC.
