Catrin - I read somewhere that the nook screen and the Kindle screen are manufactured by the same company. It is not reflective at all and compared to one of my student's Kindle, it looks the same. As for the color strip, I thought it would be annoying, but it goes off after about a minute, so it is just black. I don't even notice it. If you can get to a Barnes & Noble or Best Buy, it would really help you to actually see it or the Sony in action. The nook doesn't come with a cover. I think it should.
Also, you have 14 days to return your nook, and 30 to return your Kindle. They advertise this so you can try one and see if you like it. I didn't really think I would like reading a lot on these but I wanted to try one since I don't know anyone who DOESN'T like theirs. I was hooked within hours. I've seen all three:I have a student with a Kindle, I have a nook and I saw the Sony at best buy. I think I would have liked any of the three.
