Here the original slide (the blue rectangle) is updated to current display resolutions. In just a year and a half the number of pixels (e.g. Nexus 10) has increased by a factor of four. Both the internal memory bandwidth and the network bandwidth are only slowly improving. This increase in pixel counts makes remote Android graphics more challenging.
Another change that makes remote Android graphics even more difficult is the 60 frame/sec standard that has been adopted since ICS (Ice Cream Sandwich)..
