I disassembled a broken tablet purchased on ebay.  The plan was to fix the screen, but just can’t get over the fact that the battery in this device is six times larger than the motherboard!  By the way, the motherboard has lots of stuff on it besides the CPU and memory:  sound, video, and USB is there too.

Guess I shouldn’t be surprised since phones have all this stuff on them too, but I’m still amazed.
