Vista - Zune HD apps are here... complete with pre-roll ads.

Apps for the new Zune HD (read our review) are now available... with an unexpected "bonus": static and video ads that play during launch.
Nine apps are available: calculator, weather, Texas hold 'em, Sudoku, Space Battle 3, Shell Game... Of the Future, Hexic, Goo Splat, and Chess. They can be downloaded freely from the "Marketplace" menu on the device, and a new "Apps" menu item then appears on the main screen (you'll need to scroll down the main menu to see it, as it's pushed off the bottom of the first screen). Apps function just as you'd expect—they're small programs that look great and really take advantage of the nice screen. They are all professionally designed by Microsoft, though a couple are really worthless (ahem, Shell Game... Of the Future), but hey, they're free!
