The Kindle is very lightweight (less than less than 6 ounces). I can hold it in one hand and as long as I position my thumb next to the page turning button it doesn't matter if I'm sitting up, slouched over, or laying on my back. The screen is easy to read, although I haven't used it in very bright or very dim areas yet.
This device will hold over 1,000 books, probably more than I'll ever need. The first thing I did was "buy" some free public domain books that will stay in my library forever. However, I usually borrow books from the library instead of buying them. That's still an option! My library's Website has an e-media page where you can browse the "stacks" for something that looks good. Once you find something it only takes a few minutes to download it (if you're connected to a Wi-Fi network), and at the end of the borrowing period it disappears.
I've already used the device in the house, while waiting for my car oil to be changed, in the doctor's office, and in the car when I get somewhere early and have time to kill. I'm trying to figure if there's a way I can use it at work.
