Excuse my late-week crankiness, but my knee-jerk reaction is "this is a big deal?" Let me break it down: I UNDERSTAND that this is a "new" system, and it is an important jump forward. HOWEVER, the technology and the concept itself are not evolutionary OR revolutionary. Any dev with a good sense of the phone's kernel (or access to the major component states) could easily do this -- indeed, I don't remember the name but since the D1 we've had location-aware apps that "turn off the ringer" or "turn on wifi" or basically all the same ideas in Smart Actions.
To take the Google "special sauce" and make it AT LEAST evolutionary, so-called "Smart Actions" need to follow your daily behavior for a couple weeks, and do things like:
- construct a model of your daily routine (first email check, number of calls per day, texts, etc.)
- monitor app resource use, and construct a model of when particular apps are used and resources consumed
- proactively move apps out of memory that are idle AND unlikely to be used
- anticipate (like search fill-in) app use, and modulate appropriate resources (e.g., wifi, GPS) as needed
Basically what I'm talking about is the same thing as a "Smart House" -- it learns regularities in your lifestyle and adjusts the environment in an optimal way. At the moment, "Smart Actions" is a baby-step up from "automatically turn off wifi between 10pm and 7am." Guess I'm not all that impressed.
