Really? Then please tell me how else you can download Android apps.
Accessing the Play Store via your computer browser does not lead to any options to download apps to your drive.
And I'm not expecting Android to be like iOS, in fact that's exactly why I switched.
All I'm asking for is some kind of universal Google Store management app like iTunes.
If you want to be able to put the apk's on to your computer, you can, but it will either involve downloading them from websites like XDA (almost every free app's apk file can be found there. Pirated pay apps are not authorized, nor would I suggest trying to download a paid app outside of the Play Store.)
Or you can download the app and then simply download the apk file off your phone (usually found in System/app file directory) to your PC. I use an app called Pushbullet that pushes files from the phone to pc or from pc to phone with ease.
Once you have the apk file, you always have a backup of your app (not any saved data within the app though) on your PC. But, it really isn't needed. Every single app you download is saved in your Play store. They never get deleted unless you manually do it, so your apps are forever available to you.
If you end up rooting your phone, then you can download apps like Titanium Backup (saves individual or all apps, plus their data) or ROM Manager which does the exact same thing as iCloud (a snapshot of the entire phone when you click 'save'). If unrooted, there is an app called Helium that does similar functions as TiBU or ROM Manager.
Obviously, none of these options are as simple or integrated as say iCloud, but for now, it is all we have. Hopefully, Google institutes their save to cloud function soon.
