I would go for some affordable AR glasses + a one-hand chord keyboard. No need to hold a device in one hand and operate it with another, while standing awkwardly bent down.
I generally just thumb-type on it with the hinge bent at 180°. I have a colleauge who tried the meta AR glasses and found the display smudgey with his 20/20 vision and my quest 3 I found very screen door-y, though I will admit I liked the apple vision pro's display, I have a fair bit of pessimism about the field as a whole atm, but would like to be proven wrong
