Q My netbook battery doesn't last very long -- are there any ways to get more than a few hours of power between charges?

A Netbook battery life can range anywhere from less than two hours to almost seven, depending on the model and what the computer is doing. For example, watching videos with the screen brightness turned all the way up will usually drain the battery much more quickly than typing a report in a word-processing program.

Canon is adding another model to its entry-level D-SLR series -- the EOS 1000D/Rebel XS, whose release has been rumored on various technology blogs.

The new camera, announced Monday, includes a few improvements over the EOS Rebel XT, which it replaces, such as a 2.5-inch CMOS LCD, an increase to 10.1 megapixels, and the Live View feature. Live View enables a user to shoot through the LCD screen rather than through an optical viewfinder.
