Most users never open up their gadgets and fiddle with the innards, but some like to change the battery and repair the devices. Those belonging to the second camp won't be too impressed with the Nook Tablet, which proved quite a tough nut to crack.

iFixit's detailed teardown of the Nook Tablet shows that the device is relatively hard to disassemble, with hidden screws preventing easy removal of the rear panel, and a number of adhesive strips make the entire process quite tedious.

Of course, Barnes & Noble never meant for users to open their Nook Tablets and fix them themselves, so it's hard to blame the company for not making the device more repair-friendly. Still, if you're the tinkering type, you should know that the Nook Tablet won't make it too easy for you - iFixit gives it a six out of 10 score for repair-ability (10 being the easiest to repair).

For comparison, iFixit gave Amazon's Kindle Fire an eight out of 10 score on the same scale in a recent teardown.

The teardown didn't revealed any big surprises. The Nook Tablet is quite similar to the Kindle Fire, if a little bit thicker — it features a similar IPS display with a 1024x600 pixel resolution, and the same Texas Instruments OMAP4 1 GHz dual-core processor.
