Re: windows xp
Launched in 2001, Windows XP is the most field-proven Windows OS ever, and Microsoft users, not Microsoft, made much of that possible. Windows XP users reported problems, they vetted solutions, and third-party developers formed a rich XP-oriented infrastructure that survives to this day.
Because of XP's sprawling, global user base, more hardware is ready for XP than any other Windows OS. That univerality, alone, permits us to stay with XP, and go on to more important things. After all, we run an OS to do work, and it makes no sense to "migrate" at Microsoft urging to anything else.
