I think this is sometimes my frustration with technology. What you describe is certainly fantastic and perhaps the future as native services within iOS and Siri become more aware of what we do and put our actions into context. However, at what point do we cross the threshold of enough convenience? Is it when our devices can read our minds and on cue, do as we think?
I guess all of this is a long winded way of saying this: how much tech is too much tech for the sake of saving an extra 7 seconds from launching an app versus looking at new frontiers for technology to push human advancement?
