I will agree that the store experience is awfully horrid. It is products like this that make me think "why"?
I think Windows 8 has a lot going for it, but the store experience is so odd. It doesn't feel right ,it doesn't feel easy to navigate, and it doesn't feel fun. If I were in charge of the store experience, it would not have ended up this way. It might not be perfect, but it just feels like the user experience wasn't a focus or consideration. And knowing Microsoft, it will be 6 months before it will even begin to change.
