Here’s your chance to get an inside look at the Microsoft Zune 2 80GB model. Just to remind you, the player sports a 3.2″ screen, a 4-way touch pad, a built in FM radio and WiFi capabilities. Once removing the outside shell, you discover the control chip along with the Wolfson’s WM8350G DAC chip and the WiFi antenna, running in a WYSBCVSX2 70AN module.
