You have finally made the switch from paper books to an electronic e-reader, and you love the lightweight package and crisp images. While the rest of the family is hogging the fancy new LED TV, you can watch videos, surf the web and browse full-color books with the touch of your fingers and a little wireless access. Since you have spent the money, it is a wise idea to invest in a high-quality cover or case to protect your Nook.
Whether you have gone with the HD or HD+ models, or have opted for the simpler Nook color; covers are a necessity if you want to keep your screen sharp and your hardware from glitching. Even if you aren't clumsy, you will need to protect your Nook from any variety of encounters. A drop, even from a short fall if someone bumps into you or your cat knocks it off your chair, can ding the device, scratch the screen or knock something loose from the motherboard. A spilled cup of coffee or a rainstorm could soak your Nook and fry the circuitry. And even the least-klutzy person can't avoid the weather. Cases help shield the Nook from drastic temperature and humidity changes.
While you might not think you need protection, a case also helps make the Nook more portable. A slick neutral case looks professional and can go well with your other work essentials; the briefcase, laptop bag or padfolio. Imagine yourself perusing the day's newspaper at your next job interview or meeting; it looks professional, and you will be read up on your current events.
