In general, people are reasonable and can understand that older devices aren't compatible with some software. People have been trained by this for years. Apple is a bit of an anomaly in this way since they usually keep 3 generations mostly up to date with the latest OS, but even then, no one expects iPhone 1 to support all the same apps and functions that a 4s or 5s does. That is unreasonable. The issue with Android support is that it is completely absent. Zero support, and it's been delayed yet again. Smart money is that it will be delayed once more before Tivo supports Android Streaming. 4.2 has been out for more than a year, so where is Stream support for the devices with the most recent OS? Even more important than Android support is browser support. Smartphone and tablet rates are nothing compared to desktop and laptop numbers. At least with browser support, I could buy a Roamio and put streaming to good use.
