I originally had one if the nook color devices that I had installed the cyanogen mod 7 on and loved it. Recently though, I upgraded to the Samsung Galaxy Tab 8.9 and couldn't be happier. Great device. I personally have not been a fan of the whole 10.1" form factor especially for reading in portrait mode. The 8.9" screen is a great alternative. It still gives all of the tablet size usefulness but is a little easier to hold one handed and easier to use in portrait mode when reading.
Don't know if it will go much on a sale but I can say that it is really one worth considering.
