Many of us only use our computer to check our email, surf the net, play video games or store our music collection. We might use it as word processor or make power point slide-shows, store the photos we took on our cellphone or digital camera, and or watch movies on it. But in truth we hardly touching the surface of what it is capable of doing.
By just downloading a bit of software you can change almost anything about your computer. As long as your computer is not too old, you can do almost anything you can imagine. And so much of it is free, as most of the software can be found as freeware or you can find open source versions.
If you have a web camera, and many computers come with them built in now, one of the things you might already have tried, and if you have not you really should, is using Skype. You can have a video chat (or just audio) with a friend or relative who has Skype too no matter where they are in the world and its completely free. It can also make calls to regular phones, and these calls cost a fraction of the regular price. If you have family overseas and don’t have a web camera, it is definitely a worthwhile purchase.
