if you watched the video's you'd see that's actually a misnomer. If you have your music collection across devices (PC, mobile etc) and in a format apple doesn't approve of then you have to jump through hoops to get to the music, namely, waiting for iOS to convert it to its own DRM, or in some cases like OGG it doesn't work at all.
android has a lot of benifits (like the post mentioned above i actually do that with my tab), but for a phone i'll always stick with iOS cause they have better music management, app support and OS support then android will ever have.
App support again is an inconsistent experience on iOS as illustrated in the video's. From lack of features to poor system integration and cross device support. Then there's the cost factor.
Then wait for it to get bricked by Apple. Or when it stops working your warranty is voided. And no you still can't customise it like Android.
not to mention once you jailbreak an iphone you can do and customize the OS just as much as any android device.
