Are you dumping Vista to return to XP?

f so, you're not alone. I regularly hear from readers who have been using Vista but are going back to XP. Some are ordering their new computers with XP installed instead of Vista and some are buying new systems that come with Vista and wiping the drive and installing XP themselves. For a clue as to the reasons, check out my editorial in the November 22 edition of VistaNews:

Vista Service Pack 1 and XP Service Pack 3 are scheduled for release early in 2008

Recently reports came out that Vista SP1 doesn't do much to increase performance - but that XP SP3 does increase performance by about 10%.
