I'm a bit older than you, work in software dev and data science, main platform Linux. I'm the sort of person who has a few command-line windows and vim open, and am a keyboard fiend.

Yet...

I use my iPad a ton at home and when I travel (I travel a lot). I don't even own a personal laptop anymore -- I work on desktops with 3 monitors and at home.

I used to think that the iPad being purely a consumption device was too limiting, until I got an iPad Air 2 that was on sale at the time. It does everything I need just fine, plus it's lightweight enough to travel with.

(caveat: I don't do any dev work when I'm on the road)
