An alternative theory, however, is that Vista’s reputation precedes it. XP users have heard too many chilling stories from relatives and friends about Vista upgrades that have gone badly. The graphics chip that couldn’t handle Vista’s whizzy special effects. The long delays as it loaded. The applications that ran at slower speeds. The printers, scanners and other hardware peripherals, which work dandily with XP, that lacked the necessary software, the drivers, to work well with Vista.
I don't care how much Microsoft cuts the price of Vista, it's not worth it to go through all the problems people report having.
We usually do not have the opportunity to overhear Microsoft’s most senior executives vent their personal frustrations with Windows. But a lawsuit filed against Microsoft in March 2007 in United States District Court in Seattle has pried loose a packet of internal company documents. The plaintiffs, Dianne Kelley and Kenneth Hansen, bought PCs in late 2006, before Vista’s release, and contend that Microsoft’s “Windows Vista Capable” stickers were misleading when affixed to machines that turned out to be incapable of running the versions of Vista that offered the features Microsoft was marketing as distinctive Vista benefits. Last month, Judge Marsha A. Pechman granted class-action status to the suit, which is scheduled to go to trial in October. (Microsoft last week appealed the certification decision.)
I'll go with a MAC before I upgrade to Vista.
