I really wish people would stop using the word "modern" in marketing rhetoric as if it was a good thing, because more often than not they're using it and other buzzwords because they don't have any better compelling reasons to convince you to use their product.

No, I do not care that the newer version is more "modern", "stylish", "sleek", "clean", or any other number of useless buzzwordy adjectives. Tell me concretely what's actually better about it and how it will improve my (my, not your!) "experience". An OS should not be a fashion statement nor an advertising platform. It's a tool people use to get real work done.
