While the information has still not been publicly released sources claim that the deal is set and ad materials have been prepared. The drop could also be due to the upcoming wide availability of the company's 10 inch HTC Jetstream, which is now available through AT&T.
Whatever the case is, it is good to see the 7 inch tablet prices drop. Even though the Flyer costs $100 more than the Kindle Fire, having full access to Android's market and Google's app suite may edge this device as a better tablet choice.
