There's nothing like first hand experience, I've learned the controversy over the "crease" isn't as serious as some imagine it to be. Keyword "imagine". Once one owns and uses the device, the crease isn't a big deal. I'm not defending Samsung or advocating, but the primary feature that matters to me is the form factor and size of the unfolded display.
Being very eager to learn more about the iPhone Fold Ultra, I was disappointed as the deal breaker is the form factor. It's an odd shape, not well suited to the type of work I do with my Z fold7.
I find that the size and shape of my Z is excellent and would be even better if the unfolded display was increased from 8.0 inches to 8.3 inches. The iPhone Ultra is too wide and the display is too small at 7.73 inches.
Comparison
Surely Apple will sell these no matter its ungainly odd size, as the Apple logo alone will be enough for many people.
