Cracking open Amazon's Kindle

With the case screws removed, the Kindle's case can now be popped open.

I held the Kindle upright (as shown in this photo), inserted a thin, plastic tool (a fingernail would suffice) into the groove between the case's front and back halves, and gently pushed straight down.

Sliding the tool around the Kindle's case, the plastic catches popped loose. Care was taken not to crack the Kindle's plastic case.
