Your computer components could damage, if you do not keep it clean on periodically basis, because dust is the main cause to heat up your system and heat link to hardware failure.

• Never place your computer on the ground, always use computer table or shelf for this purpose.

Three years ago, we set out to design and build an entirely new class of device—a convenient, portable reading device with the ability to wirelessly download books, blogs, magazines, and newspapers. The result is Amazon Kindle.

We designed Kindle to provide an exceptional reading experience. Thanks to electronic paper, a revolutionary new display technology, reading Kindle’s screen is as sharp and natural as reading ink on paper—and nothing like the strain and glare of a computer screen. Kindle is also easy on the fingertips. It never becomes hot and is designed for ambidextrous use so both "lefties" and "righties" can read comfortably at any angle for long periods of time.

We wanted Kindle to be completely mobile and simple to use for everyone, so we made it wireless. No PC and no syncing needed. Using the same 3G network as advanced cell phones, we deliver your content using our own wireless delivery system, Amazon Whispernet. Unlike WiFi, you’ll never need to locate a hotspot. There are no confusing service plans, yearly contracts, or monthly wireless bills—we take care of the hassles so you can just read.

With Whispernet, you can be anywhere, think of a book, and get it in one minute. Similarly, your content automatically comes to you, wherever you are. Newspaper subscriptions are delivered wirelessly each morning. Most magazines arrive before they hit newsstands. Haven’t read the book for tomorrow night’s book club? Get it in a minute. Finished your book in the airport? Download the sequel while you board the plane. Whether you’re in the mood for something serious or hilarious, lighthearted or studious, Kindle delivers your spontaneous reading choices on demand.

And because we know you can't judge a book by its cover, Kindle lets you download and read the beginning of books for free. This way, you can try it out—if you like it, simply buy and download with 1-Click, right from your Kindle, and continue reading. Want to try a newspaper as well? All newspaper subscriptions start with a risk-free two-week trial.

Kindle’s paperback size and expandable memory let you travel light with your library. With the freedom to download what you want, when you want, we hope you’ll never again find yourself stuck without a great read.

We're very proud to introduce Amazon Kindle and we hope you like it as much as we do.
