That's why (I think) they will get less investment, like this article.
I, too, do ssh + tmux, as well as Textastic, Pythonista, and Working Copy (git), so much so that when I showed a colleague what I did, he exclaimed in an astonished tone that the only things he thought people used iPads for were email, browsing, and games.
That remark prompted me to make an 11 minute video (all done on the iPad using screen recording, Keynote, and iMovie) of creating a Linode, sshing into it, installing a user with SSH login, logging out and sshing in as the new user, installing the latest Docker from docker.com, and demoing some of the apps I just mentioned (to fit a 15 minute time budget). The latest iPads are not toys; they can be used for professional work.
With LTE access, I can easily work almost anywhere; working on a plane is much easier than with a laptop (for me - I'm pretty tall and it's already a squeeze).
