I purchased a Nook Color a little over two weeks ago. Since then I have had the following problems/inadequacies with it:

1. Technicians and supervisors who don't know the product.
Every time I call for assistance I am put on hold while techs and/or supes who have to research how to answer my question(s). This turns a basic question into a project and leads to 20-40 minute phone calls PER QUESTION! One supe actually deleted a book I paid for when all I wanted was for the sample to disappear (the sample is still there along with others that are cluttering up my device).
2. I cannot delete books or samples from my Nook Color. There is a disconnect between what shows on your computer online screen account and what shows on your device. (While I can delete samples from my account using my PC, this does not carry through to my Nook.). There needs to be a way to delete directly on the Nook and not be so dependent on online PC activity. I shouldn't have to sign on to my online account in order to delete a book or a sample. (The Kindle I used prior to the Nook allows a user to delete a book or a sample directly from the device itself.)
3. I didn't find out until after I had the Nook that the horizontal view only works on select functions which doesn't include most books adults read! Why is that? (The PC app for Nook works with a horizontal view. It would be nice if there was some consistency!)
4. The battery only works for about 5 hours. This is a real downside to the device. It requires you have your adaptor with you at all times.
5. I pre-ordered a few books and found out that no matter how long before the book is published you pay for it in advance. I no longer pre-order books from Nook. (Amazon doesn't charge for Kindle books until the book has been delivered. Most retailers have this standard business practice.)
6. The Nook app for my Android has a page swipe that has the look and feel of turning a paper book page (like the ipod). The Nook Color does not. Why not? (Again, a consistency issue.)
7. Downloading books. I have purchased three books so far. Only one downloaded as it should, i.e., without any assistance from tech support. This happened when I ordered a sample (and later purchased the book) and when I ordered a pre-order (which should have downloaded automatically upon publication but did not). It took about 20 minutes each support call to download the books. This is a deal killer for me.

I find the Nook to be too dependent on and controlled from the online B&N website. A user should be able to control the content of their device from the device itself.

I also find these issues significant, especially the number of tech calls required, the down time I have with them, and the problems with downloading.

I purchased a nook color at a local Barnes store. The touchscreen was defective within one week. The store replaced it. The replacement also started to fail within a month. As it was passed the 14 day store return policy, I call their technical support line to inquire about a refund having had this issue twice and finding several others on-line having the same issue. The attendant talked me into accepting another exchange, as they are aware of the issue and have a stock of devices that have been inspected, that do not have this issue. That device also failed within two weeks. I called once again, explained the issue and requested a refund, which was approved over the phone. They sent me an RMA and both devices were returned on 4/1/11. Tracking documentation shows they were both received in Nogales AZ on 4/5 - signed for by Perez. Two weeks later i called to find out status of my refund - I have since called 4 times over the last two months, each time after over one hour on the phone and providing the same information and tracking documentation, I was told my refund would hit in 48 to 72 hours. Each time there is a different issue, from their system not seeing the return, to the last person I talked to did not execute the refund properly. Today, on 6/3/11, I am being told I am not eligible for a refund. That an exchange voids all possibility of a refund!!! This obviously was never mentioned before at any time, or by any of the last three managers I spoke to! I do not know what to do next. Now they have my money and my returned device.
