This kind of design (task oriented vs process oriented) is appealing but incredibly hard to get right. The problem is that any time the user goes "off the rails", the experience can become incredibly frustrating since you start fighting what the device thinks you should be doing. For most items we interact with in the world, while it turns out the majority of interactions we do with them might fall into neat little buckets, the inherent human messiness means that we all end up needing to bounce off the rails at some point and what once was wonderful now becomes a nightmare.
