While Android users have been able to remotely install apps from the Google Play Store since early 2011 (when it was still the Android Market), a user couldn't remotely uninstall apps.
They also couldn't update an app (or even see if an app needed updating). This is, of course, for apps that require a manual update or if the device has been offline and hasn't received an "automatic update" (or naturally, for those who turn off the auto-update feature).
To see the new interface, log into Google Play and go to the My Android Apps section.
One "bug" we see is that although the Web interface lists "System Apps," such as the Blockbuster app on Verizon, it won't let a user uninstall updates to a system app. It just says "System App" in the Web interface installed of "Installed" (with a little trash can next to it to uninstall) or "Update."
still says (emphasis ours):
"Android apps may only be uninstalled from the device itself - there is no way to remotely uninstall items from play.google.com."
