I like the fact that it can be used to install applications without having to go through the store. It allows me to set up my own rules for what will get installed. There doesn't seem to be any way to change the size of the virtual machine (at least not in the free version). The free version limits you to 16GB of RAM so if you have more than this, you're limited to using the cloud service. If you are looking for an alternative to the traditional method of installing applications through the store, then InstallAware might be for you. We were able to use it to do some testing before deploying our application to production. This allowed us to test the application on a few different versions of Android and iOS devices without having to deploy to each one individually.
