I am sure that I have discussed about this matter in another article. And I have told you that day that there is no possibility of getting this system on your computer because this is a system created for the mobile platforms. I can imagine what for you want this system on your computer, to develop applications, but let me tell you one thing, you can develop applications for Android or for the Android based devices even if you do not have the Android system on your computer, because as I said before, this is an operating system created for the smartphones and tablets.
Still, according to an article I have read on this site there is a possibility of downloading a form for PC, whether you take it for a CD or for an USB device. Read this article and check the links provided by the author of this article. It is said there that this operating system works on a PC. We don’t know how good this system works. If you are planning to create applications, as I guessed from the beginning, please use the Windows or the iOS system that you have. Yes, you may create applications for Google, if you have a MacBook. It does not matter. All you need is to use the tools that are provided by Google. For that, you have to join the Android programmers community or developers community and to pay a certain fee to reach there and to be able to use those tools.
It is said also that the system that you can take from Android will run at the same time with the operating system that you have and you will not have to uninstall the old system and replace it with this Android OS. I don’t know in what way this could help you, but only to see how the system reacts. If you do have a smartphone that uses this system, do not try to use it on your computer, because it is almostb the same thing, only that on a bigger screen.1
