Simply speculation, but I wonder if at least part of Entourage's problems are due to Microsoft's demands for Android license fees (they claim that Android infringes on thier patents and have been suing or demanding license fees from hardware manufactures who intall Android on thier systems). Barnes and Noble appear to be counter-suing (or at least demanding a trial rather than settling) Microsoft over misuse of patents (http://www.groklaw.net/article.php?s...10427052238659) rather than pay a license fee for the Color Nook.
