Windows Vista? I dunno... it's so... 'meh.' Definitely geared towards making it sound appealing to the non-computer people, that's for sure. Thanks to ActiveWin for the info. The official announcement should've occurred by now...

"You heard it first here! The official new name for the Longhorn operating system is Microsoft Windows Vista, according to our insider sources. The name was mentioned today at the Microsoft sales conference in Atlanta. The official announcement will go live at 6 AM PST."
