There is so many possibilities with Android. An Android device like the Samsung Galaxy S3 or the Galaxy Note 2, means that it supports USB-OTG (On The Go) for example. With USB-OTG you can connect accessories like USB drives, keyboard or mouse directly to the Android device. For example a external harddrive, Flash Drive or a wireless mouse. Almost endless possibilities with that! Only your imagination is the limit.
Another thing that is great with Android is that it has a real file system that you can get to by connecting the device to a computer with either a microUSB cable or wirelessly by using an app like Airdroid.
Features like this is what iOS/iPhone miss.
Features like this makes me a happy Android user!
