Well, yes - you can use zoom function on larger screens in order to see the same amount of content, but larger for people with vision difficulties. However, two other major benefits are
- You can see more content at once (or larger media). You see more tweets, emails, texts, etc. on screen at one time on the Max phone versus the standard Pro and also video media is larger.
- Ergonomics. For some people, they just prefer a larger device. While I think the 6.1” device class probably covers 99% of that group there are some people that could benefit. My uncle was about 7’ tall and had MASSIVE hands. He couldn’t use the old iPhone 4 one handed because it’d slip right out of hands. Larger devices give him a phone he can more comfortably use.
The Max is not for me, but I see the appeal. However, I would never advocate that anyone buy the device due to all the potential optimization it could get from iOS because I don’t think Apple will ever do that.
