PROJECTING THE RIGHT IMAGE ISN'T SO TOUGH

摘要

In 1998, when I first wrote about portable projectors for use with laptops, the big news was that you could buy a "mobile" unit that weighed less than 10 lb. and cost about $5,000. In retrospect, it seems as if you would have needed a projector really badly to put up with either the weight or the cost. Like the laptops they work with, projectors have gotten dramatically smaller and cheaper, making them true mainstream products. The new $2,699 LP120 from InFocus weighs less than 2 lb., and its distinctive long, narrow shape lets it fit in a briefcase along with a laptop. If your back is stronger but your budget weaker, you can get a bigger, but still portable, projector for less than $1,000. And if you are tired of fussing with cables, some projectors let you connect wirelessly from a Wi-Fi equipped laptop.
