I love my Apple devices and I'm very pleased with the under the hood improvements to iOS 7, however I have to say that I'm no fan of the new UI. Its too cartoonish looking (reminiscent of Samsung's TouchWiz UI). I know that the flat look is in fashion now but completely hollow, outlined buttons? They look like the stick-man drawings that I come up with. I'm sure this new UI appeals to Gen Y and younger, but I have a feeling the oldies prefer the textures and skeumorphisms (obviously this is a generalization, and I do not mean each and every single older person). The new UI is a also a little too unprofessional in more formal corporate settings. I'll probably not install iOS 7 on my phone since I do presentations from it occasionally.
