Powerbook Medic has torn the Kindle Fire HD 8.9 apart for the world to peer inside. It seems Samsung has done well out of the tablet, as it's supplying — at the very least — the display, RAM and flash memory. The processor is courtesy of Texas Instruments, though.
One weird finding is that the battery is actually a split unit: it uses two separate cells, joined by a battery controller board, to provides its rather weedy 6000mAH 22.2wh power source. That's not particularly common, nor is it obvious why it's been done — space, perhaps.
Elsewhere, the teardown contains lots of nerdish findings, but there's one take-home message worth listening to: the device seems fairly easy to repair, especially the screen. [Powerbook Medic]
