Can you show me some "absolutely awesome" examples of Flat UI? Our sense of beauty and aesthetics comes from the physical world, which contains gradients, shadows, dimensions and so on. Simple geometric shapes can be elegant, but I haven't seen examples of Flat UI that is awesome as well as doesn't suffer from usability issues.
Screen with blue todos is using white text on gradually lighter background in the end the contrast is terrible IMO.
Also the gradient looks tacky and pointless
For a to do list, I think that makes a lot of sense. The items at the top of your list are higher priority, so having higher contrast text and a more saturated background up there draws your attention to the stuff that's most important.
I'll grant that -- but it's also a to-do list, which is pretty much the simplest possible application. It's a common "hello world" for GUI toolkits, and it's the first use case in the org-mode tutorial.
Is there any software more sophisticated than 'a 3x5 card with a pencil' which uses this user interface paradigm? I think any paradigm, no matter how confusing or clumsy, is sufficient for that case.
