those folding phones are permanently bulging and enormous.

I feel like I'm the only person on earth sometimes who just wants the phone to be small so it's easy to carry and use one-handed.

I want to live life when I'm out and about, the phone I have is the heaviest thing I am constantly carrying.

If the alternative is carrying a tablet then a folding phone is smaller.

What I want is a phone/wifi in a watch - e.g. Dick Tracy like.

Then I am free to wander etc.

If I need a screen then I can attach an iPad or smart glasses to the wifi from the watch.

Yes but smaller than an iPad mini.

My pockets are not wide enough for a mini but would take a folding phone - the depth is much less of an issue.
