TechCrunch has a brief piece looking at a potential cost-saving measure Amazon might be using to reduce the price of its tablet and stay competitive with the iPad. Whereas the iPad and Android Honeycomb tablets have screens capable of registering up to ten finger touches at once, Amazon may be going with a less-expensive screen that can only register two separate touches at a time.
This is all rumor, of course, as is the reported fall launch date. But it sounds plausible. Most of the time, people only need to use a single finger to tap things on their tablets anyway. And certainly Amazon is not going to be able to compete with Apple on features and sell at the kind of price they need to reach a wider audience.
And it certainly makes more sense than having screens on both front and back.
