I've just upgraded from my trusty Kindle 3 (keyboard model) which has done nearly 9 years service. I am still getting used to the differences between the devices, the backlit screen is great for reading in darker environments such as in bed at night, its less harsh than the LED in my old kindle cover. The slightly thinner bezel and touch to turn pages is taking some getting used to over the old kindles forward/back buttons on both the left and right, I havent tested the "waterproofness" of the new device either. I ordered mine with an amazon cover, the magnetised lid turns the device on when opened and off when closed and is much smaller than my old device's leather cover. Overall, it's a much sleeker package, lighter with better text quality so very happy with the purchase.
