As you may be aware, there is number of operating systems - Windows, Mac OS, Chrome, Android, iOS, Linux and others. Maybe you didn't even realize there is so many of them but hey, we don't expect you to know. You simply know what you want, well at least it is expected that you know what you need to do on your computer and that's a good start. Details are important as you may need a software that only runs on specific OS, thus giving you only one option. We believe there are always alternatives so we can gladly help you to choose the correct operating system. Keep in mind we focus on cheap or even free alternatives, which would be a bonus for you.
