I couldn't wait to upgrade to this product from the Simple Touch that had no light.  It has worked well, with no problems.  Both Nooks get a little glitchy, I've noticed, when the charge starts getting low.  I will also say that it's my impression that downloading from libraries is still relatively new process; haven't tried it yet myself, and not all libraries even offer the service.  I don't object to the ads; they are not intrusive, and I just don't look at them if I'm not up for it.  However, as with all e-readers, realize that e-books are no bargain, most of the time. Most of the books I've read cost about 10 dollars.  I've downloaded free books from Google e-books that would otherwise have cost a small fortune.  It's nice not to have to find a home for a book that I've read but don't want to keep.  With this product, the advantages are that it is lightweight, you can increase/change the font and size, which is a huge advantage if you have vision issues, you don't accumulate physical books that you don't want to keep, and the Glowlight at night is fantastic when you want to read when your partner is ready for lights out.  I had a clip-on light with the original Simple Touch and it was inconvenient as far as placement, glare, etc.  We have a Kindle e-reader as well, and I much prefer the touchscreen on the Nook to the buttons on the Kindle for page turning.
