I took apart my vita, and put it back together!

I was curious on what my PS VITA looked like on the inside. So I took a Philips head screwdriver to it and open it up. But instead of just glaring in side, I took it a little further and stripped it down COMPLETLY!!! Well as soon as I stripped it down, I put it back together and it still works.

I don't know why I did that tho.
