IMO, you can ditch a smartphone and still keep using the services. I normally keep such services on my laptop, and I just open one up when I need to use one.

It's a middle ground. I can't completely get rid of a smartphone because I'm into motorcycle touring and GPS is essential to me. I'm trying alternatives to Gmaps, but it's pretty awkward and uncomfortable.

One thing that I've done is no notification tone, and I've disable notifications for whatever selected IM apps I've got on my phone
