The problem with Metro: it's boring.

Similarly, don't you think it's time for interfaces to mature? You claim it can't evolve, that we're going to see the same interface forever. Is this a problem? There were some wacky car designs in the early 1900s before you ended up with clutch on the left, brake in the middle, gas on the right, shifter in the center of the car. People wouldn't call that boring, they'd call that mature and standardized.
No one points to the iOS interface and says "That's fresh! That's exciting! That's evolved!" It's not, it isn't, and it hasn't. iOS is exactly the same as every interface that came before it. So your implication that the iPad is king because its interface isn't boring... I'm not buying that.
That observation works better as a criticism of Metro than a defense of it.
Microsoft was clearly trying to come up with something strikingly fresh, exciting, and evolved when they cooked up Metro. If (as I'm inclined to agree) they didn't need to do that in the first place, then with Metro they didn't just miss the target, which would have been forgivable. They missed a target that they shouldn't have been shooting for in the first place.
Regardless, Metro is the idea that the interface should not distract you from the information, that the GUI doesn't overshadow the content. At a quick glance, you can easily tell exactly what you want to know. You might call it boring, others call it useful.
What would have been more boring in my opinion? Another interface full of static icons aligned to a static grid. What's a little different, a little more exciting? Dynamic icons that don't make me enter the app to know what the weather forecast will be, that don't make me open Facebook to see what someone wrote on my wall, that show random pictures from my phone in a slideshow, that show me my stock performance without needing to open the app.
Desktop shortcuts circa 1994 are boring. Metro is far from boring.

P.S. Fluoro pink on a black background with flashes of white will date faster than strawberries in the sun.
It is quite pleasing, does the job, but does not excite anyone. People like it, but do not love it. Just like the old Android design, before Holo.
