Thank you everyone for your advices. I played with my HD for a day now and it's growing on me besides the weight. I actually like the bigger screen especially since the footer seems to occupy a huge space. I have meddled with the collections and so far so good with about 200 books. And I am happy with the light which is bright and even and there are no pinholes nor diamond pattern. Not only that I don't want to hurt my husband's feeling I also don't want to go through the whole return/replace process if the Aura has pinholes, etc...
I think I might keep my HD for a few more days and see if I can live with the weight. I read a lot in bed and the extra weight is noticeable since I have small wrists, does anyone see anything like this card-holder but for ereader? It might be a neat solution for those of us who like to read in bed....
