You've gotta be kidding. What user interface tool does android + eclipse provide? There is nothing there, you've gotta hand roll it in xml. The UI tool is limited and a pain to work with.
I think android's ability to use folders to support different layouts and resources beats the file naming conventions necessary for supporting the same scenario in iOS... i.e. myLogo~ipad.png
I leave the WYSIWYG for the designer - it quickly falls apart for actually programming complex UIs. My job is to translate PSDs into working UI. There's a good reason we abandoned WYSIWYG for web design years ago and a modern mobile app is no less dynamic.
I can change the underlying grid size, padding and item spacing for every screen in my entire app in one line. Have fun doing that in iOS.
