Dear Customers,

I love slipping (滑落) into a comfortable chair for a long read—as I relax into the chair, I also relax into the author’s words, stories and ideas. The physical book is so elegant that it disappears into the background, and what remains is the author’s world.

Today, we at Amazon are excited to announce Mindle, a wireless, portable reading device with instant access to more than 90,000 books, magazines and newspapers.

We’ve been working on Mindle for more than three years. Our top design objective was for Mindle to disappear in your hands—to get out of the way—so you can enjoy your reading. We also wanted to go beyond the physical book. Mindle is wireless, so whether you’re lying in bed or riding a train, you can think of a book, and have it in less than 60 seconds. No computer is needed—you do your reading directly from the device.

We chose the same wireless technology used in advanced mobile phones. But unlike mobile phones, there are no monthly wireless bills, no service or data plans, and no yearly contracts. There is no software to install (安装，设置)。 We want you to get lost in your reading and not in the technology.

Mindle uses a new kind of display called electronic paper. Sharp and natural with no strong light, reading on Mindle is nothing like reading from a computer screen. Mindle weighs only 10.3 ounces—less than paperback—but can carry two hundred books.

Enjoy learning about Mindle and many thanks!
