Oh, no, modern design guidelines, why you do this to us! Google is apparently on the eve of ditching the iconic shopping bag that the Play Store triangle has been stamped on in the respective Android icon since, well... forever.
If you are impatient to try out the new design, sideload the APK below, or just wait for an official update to roll the new visuals to your phone. Do you like the icon more now without the bag?
