A cool layout for the wii's main menu and a really neat way to show off wii's Internet capabilities.
The Photo Channel lets you keep and mess around with photos via a SD card. The Mii channel is so cool becuase you make lil people who live in your wii and in games such as Wario Ware Smooth Moves and Wii Sorts your Mii will be used as the profile in the game and as your player character. The Weather Channel is as simple as weather it updates it's self via the Internet ever few hour and gives you the weather of your area or you can use the Glode feature to see weather all around the world (very cool).
The shopping channel I have not used yet but thats where you can buy games for your VC and demos of furture wii channels example the web browser demo is free to download for your wii.
So far the wii channels are looking very cool it's kinda hard to rate cuz it's not a game but I really like the layout and it's so user friendly so I am just going to give it a 9!
