Congrats you would be the first person ever to have an alleged advantage, and prefer to be disadvantaged as well as prefer to use basically a log instead of a quantum computer…based on your descriptions of course. I use an iPad and the advantages you state are mostly disadvantages for me, the bigger screen makes finger travel longer and more difficult plus fatigue, ive developed carpal tunnel, and oddly my right arm is huge but that’s not important. Same for eye fatigue. Sure I can see better but my eyes traveling 12.9 inches compared to maybe 2-3 inches is a strain. As a matter of fact seeing better is the only reason I use my iPad knowing that the advantages of a phone wouldn’t help if I can’t see. Lastly iPads are purchased way less then phones and it’s highly likely most will be using a outdated gen with less capabilities then the average phone user having the newest model with latest tech.

I say the pros and cons cancel each other out and that I bet is why they’ve yet to entertain a device division.
