There are some significant differences between writing apps for iOS and for Android. In some cases, Android is easier because there are more 3rd party tools. But for an app that is going to have to scale and display streaming video, and provide DRM that satisfies the content owners, Android presents a number of challenges. The broad array of different displays, different processor architectures, and the rapid evolution of the OS itself all make such an application challenging on Android. There are many Android apps, for example, that don't work correctly on Ice Cream Sandwich. Personally, I believe we would have seen an Android Nomad client by now were it not for ICS and the many changes implemented in that release.
All that being said, count me in as someone that would love to see a Nomad client for my Droid DNA (which has a 1280x1920 display and runs ICS).
