What's different? Nexus 7 (2013) vs Nexus 7 (2012)
The Nexus 7 (2013) has quite a few enhancements. Here's a list from Engadget showing the comparison which you can check out below.
The new tablet has a new high-def display, slightly higher pricing, better cellular, WiFi, cameras, resolution, memory, plus lower weight, thickness, and sadly, battery life. I'd recommend anyone looking for a $230 tablet to check this new Nexus 7 out.
