Yes indeed! This is awesome, thanks for the initiative!
A few things I noticed reading it all through:
- Sync with a Mac IS official, through the Windows Phone 7 Connector. MS made it official about a month ago, I think.
- You may want to include YouTube (and possibly even Flash and Silverlight) in your question about Netflix. They all have essentially the same answer, and all have been asked MANY times.
- In your email section, you may want to mention that IMAP is not supported either, and that the supported types are exchange, Windows Live, and Gmail. Windows Live also has an email forwarding service, in case anyone was wondering.
That's all I've got for now, and I'll probably contribute some original topics to this later, but you've done a wonderful job hitting on most of the big things. Thanks a lot, LittleDaveJ!
