Quite the contrary, I think Apple's design do look more modern. Especially if you compare them to Metro. Metro can be more functional (especially on mobile devices) but to casual users (as in, most of the computer/gadget users) it's not as comfortable. Also, Metro do look cold. It's a colorful interface, but it has no personality. You just do whatever you need to do and be done with it, but you still don't feel that process was natural. You need to learn how to do the things you want to do and after awhile the whole process becomes boring. You don't feel anything while you're using your device. That's not what Apple is aiming at. Apple's design is the way it is because Apple wants users to engage with the device they're using. They don't want you to just do your job and get on with it. They want you to feel something while you're using it, they want you to enjoy it. Metro doesn't achieve that, and frankly, it doesn't seem like Microsoft was trying to achieve something like that either. Plus, because of all this skeuomorphism thing, this "high-tech" devices doesn't seem scary to casual gadget/computer users. I know a lot of people who don't use a particular device because they're afraid they can mess things up or they think can't use it. Devices intimidates them. Apple's devices are not like that. Even if you haven't touched a single Apple device nor seen one, once you get one in your hands, you have this feeling of similarity. You feel like you've been using the device you're holding for a long time, and whatever you want to do, you just do it naturally and the device reacts. You almost never need to learn anything. That's something unique to Apple and is one of the many reasons why they're so successful.
