Do you have a Google Apps application that you want to use on your desktop? I found this wonderful app that will let you play your favorite mobile apps on your PC or MAC. It is called BlueStacks App Player.
You can download the installation file from the BlueStacks website and install it just like any other software. Just like in devices using Google Apps, you will be prompted to log on to your Google account or make a new one if you want to in order to use this app.
The BlueStack app can be used in full screen but if your desktop PC specs can handle the load, you may opt not to do that and do other tasks (just like what I am doing right now while writing this post).
This program is currently free because it is in beta. If you want to try it, better do it now (or you may have to pay to download it later).
