Free: It's the magic word for an ever-expanding wealth of downloadable software and online services. Free doesn't necessarily mean good, however, and hunting for freebies can mean sifting through a lot of junk. That's where we come in. We surfed, clicked, and installed to find sparkling free gems capable of planning your time, keeping you in touch, and tuning and securing your PC, not to mention glitzing up your desktop, helping you stay productive, and entertaining you with music, videos, photos, and games. We paid special attention to programs and services you may not have heard of before.
