Why Is there such a huge difference in terms of speed and responsiveness? I mean didn't they just made the old one into an app instead of built it right in? why does that affect the speed so much?
The old music + videos hub is still built into the OS.
The old music + videos hub is still built into the OS. I guess they didn't spend much time on building the new app and integrating it into the OS yet (For example, when you open a downloaded music file from IE, it still opens in the old hub).
