Microsoft's Zune player is starting slow and the need to ramp up their technology. Sandisk is now offering a great Wi-Fi player with the Sansa Connect. Wi-fi is still a technology Apple did not put in the iPod. But I assume a Wi-Fi iPod is around the corner and it might play well with the Apple TV.
