We just opened it about an hour ago. The 7" screen is nice and bright. It's a little heavy but feels very solidly built. The back is rubberized so holding it is easy. The only controls on the body are the power button, usb plug and headphones jack. There does seem to be a hole for a camera in the upper left corner but I haven't read anywhere of it including a camera. This must be for the next revision or software update. When I turned it on, it let me choose my wifi connection and then logged in. It took about four minutes to download and install the new updates to the Fire. Then it allowed me to keep it register to me or I could deregister it and tie it to my wife's amazon account. It was a very easy setup.
After that the main bookshelve showed up. It already had access to amazon store. Facebook and a few other apps like email where already installed. A couple of the books we've read on the computer kindle app were already there too. I downloaded the free version of Angry Birds and setup my Netflix account. We played Angry Birds and then the kids watched Gnomeo & Juliet for a half hour. The picture was sharp and clear with no stops or breakup. The speaker was a little tinier sounding but I would use headphones anyway.
We tried the built in web browser and it was incredibly fast. Zooming in and out was very quick. The keyboard was very responsive. Youtube played very well in full screen. We tried some of the books and it preformed well. Since this is our first touch tablet device, it is taking a little getting use to controlling the device. There is a little big of a lag or maybe we just haven't figured it out yet.
Overall, it looks like a real winner for Amazon. There is so much stuff to run on it. I may have to buy another to keep the kids from fighting over it. We are still learning what this thing can do. Personally I believe this is the first real competition to Apple because of the Amazon marketplace. Movies and mp3s are cheaper than on iTunes. They have a lending library and lots of storage in the cloud. So far I'm impressed.
