The store is damn ugly now. I don't know what they were thinking.
The horizontal scrolling is unnatural and unfamiliar. Users expect to see horizontal scrolling in three situations:
- Slideshows, where it actually make sense
- Websites that are designed way too wide
- more "creative" websites that do this intentionally (they're annoying, not creative)
The last icon to the right shows only half of the icon, which I suppose is to indicate that scrolling is possible, but it's visually disturbing, making the layout look "broken".
It's even worse on the iPad version. As an app author, it concerns me that the new layout makes app discovery more difficult.
It's silly that the store is still integrated into iTunes. Break it apart so that the store is separate from iTunes.
As for the iTunes part of it - well, I can't comment, since I don't use iTunes for music. I don't play music on my computer, so it's a bunch of unnecessary visual clutter when I want to access the App Store to find iPhone/iPad apps.
I guess it's a great opportunity, though, for third-party app-discovery websites.
