Microsoft needs to come up with a proper name for Longhorn, and soon, because it's in the middle of creating a series of marketing schemes for PC vendors towards the end of this year. The scheme allows PC manufacturers to dub their machines '[Whatever it'll be called] ready'.
Now press reports claim that Microsoft has come up with a proper name for Longhorn. The surprise is that it apparently isn't going to be called 'Windows 2006'. According to the wire, Longhorn will be officially called 'Windows Vista'. There is currently no confirmation or announcement from Microsoft on this, though.
Microsoft is expected to release a beta version of Longhorn / Vista next week, and the retail version of the OS is still slated to appear in the second half of next year.
