In our forums, poster MarcMaiden happened to have a conversation with a Microsoft employee who stopped by his work (AT&T). The MS employee, who will remain anonymous, was "...going to a few stores and retailers to see what kind of response we were getting...looking for feedback to send to the developers to know what exactly they should work on."
Marc asked him a few questions about the platform and the answers are quite revealing, namely about that rumored January firmware update which should bring quite a bit of functionality to the OS.
Q: Why isn't there an option to add custom ring tones?
A: Microsoft is working on an application that will be included in an update in January which will allow the consumer to edit, customize, and add ring tones of their choice. This app will also include a user "library" to search and download ring tones.
Q: What about turn by turn navi?
A We are beta testing it right now. again, ETA January.
Not really too much info, but with Copy/Paste, custom ringer support, turn by turn navigation in Bing, Skydrive and possibly multi-tasking support (via hubs), this should be pretty huge. Not yet a member of forums? Hop in and join the conversation!
