Thanks Milhouse for the heads up on this interesting post by Paul Thurrott updated on the 14th of January.
From Paul Thurrotts SuperSite for Windows: If youre a Net junkie like me, youve probably seen screenshots that reportedly expose upcoming user interfaces for the next two versions of Windows (code-named "Longhorn" and "Blackcomb"). You might have heard of internal alpha builds of either OS, and maybe, just maybe, youve seen the infamous Blackcomb movie thats making the rounds as well. Ive spent the past few months investigating all of these things, and after speaking with several Microsofties and uncovering the truth behind the wild stuff thats available on the Internet, I thought Id provide a little heads-up on whats really going on with the next version of Windows.
Chances are, everything you know is wrong. But I do know this: As of this date--mid-January 2002--every single screenshot youve seen that purports to be Longhorn or Blackcomb is either fake or actually shows something other than those OSes. Every single one. And there are no builds of Blackcomb floating around, internal or otherwise.
Read the rest of the report here which attempts (successfully) to throw some light on this next version of Windows.
