Standing out visually is helpful for branding, but the unique designs that succeed usually occur when presenting the relevant data in a useful way. So understanding helpful mappings is key.

For example, I switched to iTunes when it was first released on Windows mainly because of the “artist | album | song” as a row of lists interface. It wasn’t a new interface: Smalltalk used something like it for code, and OSX had it as a display option for file browsing before then too I think. But it was such a big improvement over Winamp for quickly finding the album or song I wanted to hear. IIRC Winamp at the time was a direct map over folders, and they were just vertical trees. When I switched, I had to do a bunch of tagging, but it was still worth it. If iTunes had used a gmail-like “tag and search” interface, I don’t think it would have been as compelling. I’m still waiting for something like it in Windows Explorer.

i believe that inteface is called 'miller columns.' didn't realize what i was missing til i used the OSX Finder.
