The Zune 2 is Microsoft's second iteration of its Zune player. The first was a nice try for microsoft but it was the size of a brick and kind of hard to use. The mew model on the other hand corrects most of the problems and is alot smaller so it actually fits in your pocket.
First the Zune's biggest selling point over the Ipod is its inclusion of WiFi allowing you to share songs with other zunes, this is a great feature but occasionally the wifi can be slow even if your friends right next to you. Another great feature is the size of the screen its absolutely huge for an Mp3 player you can actually watch your videos comfortably without squinting. The Sound Quality is excellent and the included ear buds are great they block out almost all noise and are magnetized on the back to prevent it from getting tangled up which is useful if you carry it around in your pocket or backpack. The only glaring negative i can come up with is the click pad, this time its touch which is nice but occasionally when you try to click on something to select it you'll instead end up clicking a direction it happens sometimes but is nothing major.
Pro's: Huge screen, Excellent sound quality, Plenty of storage space, WiFi
Con's: Click pad is questionable sometimes, Wifi doesn't always work
