In your experience, do users of iPhone apps enjoy using an app with a "cool special background", like the one below, or do patterned backgrounds distract from the overall point of the app?
I've seen some very slick looking apps online, but do not know if such backgrounds actually add anything to the app, other than making it look more professional. For example, do they make text harder to read?
I'm including an example of one of my screens. Would you replace the white background with one of the patterns above, for example graph paper?
