Buzz is building around Microsoft's most anticipated player Zune, I came across this two video clips, showing the Zune in action, one of the video shows how the buttons work, the other shows two Zune sharing music. Although the sharing is limited to 3 days or 3 tracks whatever the case...It has Wi-Fi, 30GB hard-drive, and rumor has it that, it has no wheel, instead it has five navigation buttons.
