That Wheel Thing: Not so cool. Turns out that theres no touch-sensitive scrolling feature here - its shaped like a wheel, but its really just buttons. Zune has a menu button on the left of the circle, scroll buttons within the circle, and a play/pause button to the right of the circle. Theres also a hold switch just like Apples on the units top, near the headphone port. You press up and down on the Wheel to scroll up and down through menus.
General UI: Cool-ish. Think iPod, but in reverse: white text on black screens, but with a very iPod-like menu hierarchy. A white and gray gradient highlight bar fades in and out as you transition from level to level of the menus - a slightly futuristic and definitely nice visual effect. Theres also user-customizable wallpaper, which could compensate for the fact that the screens otherwise look pretty boring - there arent any dividers for top, bottom, or side interface elements, just text.
Scrolling UI: Cool-ish. When holding the scroll button to run through a huge list of songs, the screen superimposes the current alphabet letter over the right side of the song list to let you know quickly how far youve moved.
Album Art: Cool. Zune displays album art in a full-screen-width cube at the top of its screen, leaving room for an MTV-style black track details bar at the bottom, along with a battery life indicator. The album art is significantly larger and more detailed than the iPods largest such display, thanks to the size of Zunes screen.
Integrated FM Radio: Cool-ish. Yes, like virtually every other iPod wannabe out there, it has one. Like the fading gradient highlight bar, however, this one is stylish in a minimalist way - large numbers on the screen, with a fast-moving bar and numbers representing the FM dial. Think Apples iPod Radio Remote interface, but with more motion, no background art, and no preset details at the bottom - you can pick North American, European, and Japanese frequencies.
Wi-Fi: Eh. Apparently you can use the Wi-fi feature to loan other Zune owners music for some short period (a day), giving them the opportunity to buy the tracks themselves from the Zune music store. While this is a cool idea, and could work well for ubiquitous iPods, it gets an eh here because youre unlikely to randomly bump into other people who have Zunes, and unless Microsoft actually gives away music, youre even more unlikely to find people who are willing to purchase tracks from its latest music store. You may also be able to spool Zune music to a Wi-Fi-enabled Xbox 360, which again is a cool idea, but requires a $100 wireless adapter and the $300-400 console. (Its unclear as to whether the hard disk - part of the pricier $400 package - is required.)
Other Details: Not so cool. Zune is a bit bigger than a standard 30GB iPod, and apparently made entirely of plastic. In addition to the Music menus, there are Videos and Pictures playback interfaces, which arent as simple as Apples. Rather than using the iPods single-line Rolls of Film + (#) display, photos can be shown in a list of individually-named folders with a second line indicating the number of pictures per folder, which unnecessarily uses up screen space. Other views are available. Videos also use two display lines a piece. An Extras menu provides access to the Radio feature, and presumably features added by future attachments or firmware. Settings lets you adjust the menus, the internal LCD screen, sound effects, the radios frequency tuning, and more.
