A 15" laptop would need something like 4000×3000 pixel to equal the current iPhone’s resolution. (A 30" screen would accordingly need something like 8000×6000 pixel.) I don’t even know whether that‘s currently feasible below the price of a small car or something like that. I wouldn’t expect 300+ ppi (“Retina“) screens anytime soon but resolution independence sure would be nice. (And later maybe some 200+ dpi screens.)
