The wm 7 ui is typography based with minimal visual flourishes and virtually no icons.

Its very different than any mobile ui out there. I really enjoy the experience on my zune hd and that's a preview of what wm 7 will be based around. From what I've experienced (people who have never seen this type of ui before), people seem to be intrigued and curious by it. If the mobile team at microsoft is paying attention to details in the way the zune team did leading up to the launch of the zune hd, then a lot of doubts people have about this platform will be gone.
