We continue to be disappointed with the FAOTD program. It began promisingly enough, with Angry Birds Rio, but we've gotten tired of the endless games or niche apps, and especially apps which have no uptake in Google Play, and seem to be FAOTD as a desperation move by the developer.
We'd like to see free versions of say, Office-compatible software or useful utilities such as CalenGoo instead of niche apps or endless games (we just assume every day that it's going to be a game; it's gotten that bad).
Amazon.com opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. Amazon.com has responded to the lawsuit in the same manner.
Apple has already lost a portion of that lawsuit, which said Amazon.com had participated in "false advertising."
