While Apple seems more refined in many ways and pull off consistency with simple but rich designs, I feel like they've been going overboard with rich textures in the post Jobs era. Applications like Find your Friends on the iPhone, iCal and AddressBook on OSX Lion sacrifice simplicity and east of use to emulate "real world"-ish look and feel with faux leather textures that serve no other purpose than to "look" nice.
The more I see Metro the more I like it.
"There are no gradients or design elements that would look dated 5 years from now."
Using just pictures and fonts does not make your design timeproof— for example, the classical IBM ad definitely looks antiquated nowadays:

There is no such thing as a design which can always preserve its polish, because design always inscribes itself within a greater cultural trend which is inexorably a product of its era.
The point in question is my uneasy feeling at the increasingly intricate designs dominating the iPhone for both third-party and Apple's default apps that seem to distract from a focus on utility and functionality. Of course, that's not entirely a valid logical position but my subjective opinions so I do concede.
I hope the explanation is that their web publishing framework just sucks and has no oversight, because it would be troubling if the designers/bloggers missed this.
