I like the idea of tiles but as they get more numerous and varied (with photos and custom apps) it starts to look like the classified ads. I don't know where to look and feel disoriented.
Yes. The white on solid color tiles look good with a couple of colors on the screen but once there are 8 animated tiles in different colors and background images on the screen, it looks more like the TV ads on Idiocracy: http://creativebits.org/files/idiocracy-tv.jpg
How is this different than the iPhone or Android metaphors? There you have a bunch of tiles that are all the same size. Is that more confusing than different sizes?
