Now, the folks over at Gadget Love have made a GIF that shows the evolution of the Nexus handsets, right from the Nexus One to the Nexus 5. In just 3 seconds, the GIF shows how much Android has changed from the Nexus One days. Gone are the trackball and capacitive buttons for a virtual navigation bar and much smaller bezel space. The screen and overall dimensions of the handsets have also increased tremendously, with the Nexus 5 being the biggest of the bunch with its near 5-inch display.
