Analyst firm Garner has confirmed what I (and most people in the software industry) knew and felt for years, that we should all treat Windows as beta software.
A rule of thumb that I was told many years ago was that it always take Microsoft three versions of any products before it is usable. Just look at the original Windows, version 3.1 was the one most adapted. Then the next phase was the Windows 9x series which accumulate to Windows Me. Then the “proper” OS that was NT. Ignoring NT 3.5 for good reasons, it was Windows XP that gained most users’ trust and started the migration from Win9x to full 32 bit OS.
