Which PC Do You Need?

We examined and lab-tested several types of computers to find out what you can and can't do with them, and to learn what trade-offs you make when you choose one over another. We scrutinized four categories: big tower PCs; small systems, including all-in-ones (units that integrate case and monitor); wide-screen desktop-replacement notebooks; and beige boxes. Using test systems in each category, we compared size, performance, upgrade potential, overall design, and price. We discovered that no matter what your quirk, there is probably a PC--whether huge or tiny, portable or nearly immobile, fully equipped or basically stripped--waiting out there for you.
