With only a little sense of self aware irony, one thing I hate about so much dialog these days is how vehement opinions are. I don't particularly like the rounded corners, and think it's a regression. It's also... fine. It's not the difference between usable and entirely unusable. And I see this kind of attitude all over the place now. A slight change, some slightly non-ideal behavior and all of a sudden a product is THE WORST THING EVER. We will be ok with inconsistently rounded windows. I think people need to be a bit more tolerant of design decisions that are opinionated, and likely worse but also not breaking.
