Well... we've all got different requirements, different perceived requirements and varying levels of buying into advertising and skills sets.
I'm happy with a regular mobile phone to make and receive calls as well as desktop computers for anything that I'd need to use one for. I see no reason to be "always connected" in fact I hate the idea of it. For someone else though it would be totally different. They might want to be constantly connected. That and the stream of information that I despise they may really like.
The extent of a persons "digital life" will likely correlate with how much they make use of the outlets that are available.
Laziness, convenience, inability, efficiency. They all come down to preference and what a person is used to doing or is prepared to do. While one person might balk at the idea of asking for directions or using a printed map when they can instead use a smart phone another may enjoy having the skillset to navigate their surroundings and be happy to engage with other people to find out more. This is one of those situations that being "more connected" ends up with people being "less connected" - instead existing in a digital microcosm. If that works for them, then great. The rub comes from an assumption that others can not do without these tools. That though is an issue of advertising and societal shifts.
