You didn't really think we'd let a new gadget emerge without a shout out to the crazy tech surgeons at iFixIt, did you? Having already taken apart Amazon's Kindle Fire and laid out the device in pieces, iFixIt has turned its attention to Barnes & Noble's Nook Tablet, the $249 competitor to Amazon's $199 slate. It's a good thing they did, too, because tearing into a Nook Tablet isn't for the faint of heart and you're likely to kill your device if you try this on your own.
iFixIt located a pair of "sneaky screws" hidden beneath two small circles nestled on each side of the microSD card slot. These have to be removed before you can even think about tearing open the Nook Tablet. Once extracted, iFixIt had to pry the case halves to separate them from each other, twist a Torx T5 screw, and pry some more to "free the front bezel from a sticky situation."
There weren't any big surprises found inside the Nook Tablet that we didn't already know about, though it's interesting B&N labeled the battery as "NOOKCOLOR." If you're curious about part numbers, iFixIt found a SanDisk SDIN5C1-16G 16GB flash memory chip, Texas Instruments 6030B107 power management IC, Hynix H9TKNNN8P 1GB DDR2 RAM, and a few other odds and ends.
All in all, the Nook Tablet is tougher to disassemble and service than the Kindle Fire, according to iFixit, who gave it a repairability score of 6 out of 10 (10 is easiest to repair), compared to the Kindle Fire's 8/10 score.
