I have the Nook Color and just bought the Nook HD+. It is a larger form factor than the HD. I like it is 34.4 X 35.8 X 0.80 mm larger. It weighs 2.4 ounces more and displays in HD. I love it. The weight difference is not noticeable to me unless I hold them at the same time. The HD+ has the same basic form factor as the Color and Tablet. The HD is different so I can not answer that question. I did not like the look of the Nook HD. I like having the same form factor in a larger size.
