On my desktop PC, Bluestacks fared better. I could install apps from a handful of markets (the software lets you choose from sources like Google Play, Amazon’s Appstore, Get Jar, and 1Mobile Market), and there were no major issues running them. Even so, Bluestacks has some inherent flaws when it’s working properly. When browsing Bluestacks’ app store, there’s no way to view a description of individual apps. They simply install immediately when you click on them. (The workaround is to go into individual stores, such as Google Play and browse that way.) Also, a lot of Android apps aren’t optimized for larger screens, which isn’t Bluestacks’ fault, but even some of the ones that are don’t display in tablet mode.
