Demand for computers with 64-bit processors is nudging more PC buyers to go with Windows Vista, despite its negative reputation and continued demand for Windows XP, writes Jon Bach, president of Puget Systems. "There is a 64-bit version of Windows XP, but driver support is so poor that it is rarely a feasible option," Bach explains. Driver support for 64-bit versions of Windows Vista is much better, he notes, adding that it's "funny to think that the availability of 64-bit drivers is quite possibly the largest factor 'forcing' people to adopt Windows Vista."
