Open source gadgets mean any software whose source code is made available for use or modification for users or developers.
The advantages of the open source gadgets are evident: since everyone can modify the source they are improved continually by software communities and the vast majority of open source programs are free.

Being free is a huge advantage sometimes you, the computer owner want to do simple, one job, like editing a document or a picture, and you don't want to spend a small fortune doing it, so the free open source programs are your best friends.
The most of the open source gadgets were initially created for Linux owners, but in the last period of time more and more open source gadgets were developed for Windows. And in this article I'm going to tell you about the best gadgets for Windows users.

The free and open-source software that you should use are: web browsing - Mozilla Firefox, video player and video podcasting: Miro, instant messaging: Pidgin, e-mail - Mozilla Thunderbird, RSS: RSSOwl, peer-to-peer filesharing: Cabos, video player - Media Player Classic, DVD ripping and video conversion - Media Coder, word processing suites - OpenOffice.org, podcasting: Juice, sound recording: Audacity, photo editing Paint.NET, FTP - Filezilla.

I'm currently using: OpenOffice.org to write and manage documents, Filezilla for FTP connections, Paint.NET to work with graphics and Thunderbird to read and write emails.
Don't aspect the open source gadgets to have as many features as the paid ones, after all you get them for free.

Well known are the open source Google Desktop Gadgets like: Google-battery (Never lose track of your power. Always tell you how much battery power is left) Google-calculator (Calculator gadget for Google Desktop), Google-cricket-news (Displays cricket news headlines and images), Google-cricket-videos (the same like the previous only it displays videos on your desktop), Google-desktop-sdk (Complete examples of using the Google Desktop Gadget APIs) Google-digital-clock (is one of my favorite desktop gadgets, it is obviously what it does: it shows time, but in a beautiful manner ),Google-flower-pot (It is a Virtual Flower Pot which will grow to full bloom right before your eyes if you give the flowers some water using your mouse like the old Tamagoci games), Google-moon-phase (Displays the moon's current phase) and Google-timezone (Find what the time is in different locations).

For now the most used software's are the paid ones, but the free open source ones come fast from behind. Each day communities of developers work on them for us to have a better experience and free programs.
