Game time! Let's play "Spot the Differences!" Can you tell these Kindles apart?

Hint: one of these tablets is not like the other.

Give up? Well, we have Kindle Fire HD, a non-HD 2012 Kindle Fire, and a Nexus 7. You can tell apart the non-HD vs. HD Kindles by different camera placement and a small size discrepancy.

We'll be including some non-HD Kindle Fire tidbits in this teardown, as it largely hasn't changed from last year's model.

Thickness comparison (top to bottom):

Nexus 7: 10.4 mm

Kindle Fire (2012): 11.43 mm

Kindle Fire HD: 10.3 mm
