That will help Windows 7 succeed, but Tom Reestman pegs the real driver ...
... The biggest thing Windows 7 has going for it, by far, is that while after six years XP was showing it’s age, after nine it’s almost comical....XP is going the way of Windows 98.
When Win 98 first came out, it was pretty good by the standards of the day. After years of patches and virus attacks and disinterest it was a broken wreck.
XP's not quite there, but it's close. Most of all, it's a security nightmare. Antiviral software bogs down most any machine.
Windows 7, aka Vista 2.5, will be a great success -- because XP is finished.
