Bluestacks has come a long way since its original app player in 2011, which was notable for being one of the first methods for running Android apps on Windows. Now it's launching Bluestacks 2, the latest version of its platform with one big upgrade: the ability to run more than one Android app at the same time. The new app, which is only available on Windows at the moment (Bluestacks hit Macs in July), adds a tab interface for jumping between multiple Android apps. Basically, it looks a lot like a web browser. Bluestacks 2 can also play mobile ads in separate tabs once you click on them, which will hopefully keep them out of your gaming time.
