If you got worried when Amazon’s Kindle went out of stock a bit earlier, you can rest easy as they have just announced a brand new model. The new Kindle (yes, it’s just called the Kindle) comes in both the classic white and now graphite colors, is thinner and lighter than the predecessor, and starts at a great $139 price point. There are both Wi-Fi and 3G models with the 3G models using AT&T’s network like the Kindle 2 did. Want raw specs? Well, the device is 21% thinner, has an even better contrast, doubled internal memory at 4GB, and it’s a bit quicker all around — faster page turning! It’s available August 27th in the US and UK. So, interested or what? Or do you have iPads to take care of your reading needs?
