As some of our astute readers have pointed out, the Zune 2 looks like it will support a Wi-Fi text messaging service. The extract from the leaked support document details an inbox feature, which "is where customers can send and receive text messages with other Zune users." The added functionality would sure make the social a lot more social, but the exact details are not clear.
Apparently, there are three types of messages, including text, artist or album. What the artist and album message formats will allow is not clear. (Simply a message with the information seems unlikely, but anything beyond that also seems a little unlikely). What has not been touched upon is a method for text entry; we sure hope there is some form of a solution to make this doable. Given the hardware infrastructure we cannot see a solution, but we'd love to be proven wrong
