No.
nope the nook is much smaller than the nook color! dah!
Yes, same dimensions.
Yes, the only difference between the two devices is that one has glow light and another doesn't. SO yes the glow version can fit.
It depends on the type Kindle case to fit a Kindle Fire.
YES
Yes it is but there is a kindle just for reading books but the tablet can do more than books.
no the buttons will be covered
I don't think so myself. The iPad is a little bit bigger. However, Amazon does sell Kindle cases. If you want one, go look at Amazon.
no
Try to find a book case that will fit into a nook or cranny, that is also large enough for your needs. This obviously depends on the size of your overall apartment.
yes it is the same size but the lg rumor cell phone charger will only output an amperage of about 1A where as the stock nook color charger outputs around 1.8A so the charging speed and power of most cell phone chargers that fit in the nook will not be enough to charge it efficiently, i recommend buying another nook charger to save yourself the hassle of extremely long recharge times
Depends on the case design, but it will not be a snug fit since the K2 is a bit larger. Have you tried looking at some of the smaller manufacturer of Kindle covers? I've dealt with Joe V. Leather before and they custom fitted my K1 into one of their cases. Turn around was decent and price very affordable. Not unless it's a very loose case (in which case, why bother?). If you look at pictures, the K1 and K2 are different in shape and size, so I'd say don't try.
