Fuji X-T1. Cheap when bought refurb/used, weather sealed and rugged, all the features you'd ever need, WiFi connectivity so you can transfer images across to smartpones. Thanks to regular firmware updates it has barely aged since 2014 and even had some autofocus revamps. Definitely the closest thing we have to the Thinkpad.
