Yeah; especially given the number of pixels we have at our disposal. Old UI screenshots look simple but they had to work at tiny resolutions compared to modern user interfaces. I remember when 800x600 was considered luxurious.

Web apps also can't use a lot of native shortcut keys to build keyboard-friendly UIs. Its rude to override the browser's right click menu. Alt-anything might bring up browser native controls. Ctrl/Cmd+S is owned by the browser. And so on. Some of this stuff you can override, but even if you do, users never experiment because those shortcut keys basically never do what you expect.
