I'm similarly anomalous, for whatever that's worth. I prefer a feature phone and sometimes a tablet as well when I'm out but wanting some basic tools and connectivity. I use high-spec desktop workstations for most real work, proper servers for shared facilities and larger-scale storage, and a mid-range laptop for things like meetings or on-site client visits.

I don't really see the attraction of smartphones given the alternative devices you can use today -- they're sort of half-OK at lots of things but not really great at anything, and a lot of them seem to have worse stability, security and privacy problems than every other device I use put together.
