If it's true that it can run Android apps, you can use an offline navigation application that uses OpenStreetMap data.
For example MapFactor Navigator provides turn-by-turn navigation and works reasonably well.

I used navigation as an example. In general though I really don't get the idea of wifi-only table. I commute regularly and get most of my non-coding work done during that time; e-mail, responses, catching up on news and a whole bunch of things. Also when I'm out I carry my tablet around, just in case.
And I have a dumbish phone which I use for making/receiving calls :-)
(Also an advantage over using the phone for data is that by using a data-only SIM, your ISP won't do some nasty stuff like blocking VoIP. In the end, I may go back to a dumbphone, too.)
