Google has made strides to move many of the Android users over to the Android 2.0 environment. Google recently released statistics that show that 50.4 percent of all Android devices that connected to the Android marketplace in the past two weeks of early June 2010 were running Android mobile OS 2.0 or higher.
There has been concern for a growing divide in capabilities between more modern forms of the OS and earlier incarnations. These recent statistics provide a sense of comfort for such concerns–that users are moving towards the more advanced 2.0 environment and upgrading their software (and in some cases, devices).
