Microsoft’s Windows Phone team on Twitter said that it's dropping the cumbersome "Series" from its "Windows Phone 7 Series" name -- putting an end to one of the more difficult Microsoft tongue-twisters we've ever encountered. Microsoft didn't give a reason, "Windows Phone is an OS, it's not a phone. The idea was that we needed a handle to refer to the devices that ran Windows Phone 7 -- the family, in essence," he said. "Now, in a lot of the coverage and a lot of the usage cases, that context, I think, got lost. People got to thinking that the software was Windows Phone 7 Series, when really that was just an effort to refer to the devices that would be running Windows Phone 7."
