Without connectivity, it’s just a computer with an annoyingly small screen and keyboard that needs a dock to be truly functional for the things I want to use a computer for. (And even then I am stuck with a sub-optimal desktop environment.)
If it’s not a phone with mobile data (so it can be a hotspot) that works … then it is basically an expensive paperweight.
And in my case I can only make calls if I’m within a few hundred feet of a tower. That effectively makes it useless.
