Kindle: Amazon's New Wireless Reading DeviceThis is a wonderful invention! Being able to download books and newspapers is quite convenient and the Sprint EVDO connection is very fast and much easier than having to hook up to USB.Being able to order items from the kindle itself is a great feature especially when you are away from your computer. The audio function is a very nice feature for music while reading and audio books and will be even better when it has more sphisticated controls. Controls however for turning pages are not well placed and cause one to often "accidently"turn pages. The "bookcover" is not well engineered and come loose or inadvertently opens the back over. Would be nice if it were as small as Sonys ebook, but its current size is quite adequate especially with its additional features.
