One remark: 'See it in action' opens the Zune desktop software and then gives me an error "This can not be displayed" in my local language. Is that becaus I don't have a phone? The should stille be able to explore the apps rigth ? I'm not able to go to 'apps' under the marketplace section, the link is just not there.
Interesting, what is your locale? I suspect it could be that the marketplace is not available in your locale??
