Are screensavers still necessary in 2007?

Screensavers were initially invented as a way to prevent ‘burn in’ on computer screens. Burn-in is what happens when a single image is displayed on screen for an extended period of time, resulting in a ‘burn’ of that image permanently damaging your screen.
Today, with the prevalence of CRT and LCD screens, which are highly resistant, burn-in is not much of an issue.
However, screensavers also serve another purpose: entertainment.
There are many animated and complex screensavers which people put on their computers and watch them as their computers idle. These more complex screensavers do however use up a good deal of CPU, and are not strictly a good option.
A couple alternatives, are either a blank screen, or, better yet, a wallpaper screensaver. These screensavers display a rotation of wallpaper images on your screen, which are both entertaining and use little CPU power.
There are many wallpaper screensavers which cater to all different tastes, including celebrities, cars, babes, nature, cartoons and many more.
So rather than having a blank screen, or a boring screensaver, try a wallpaper screensaver.
