Cost of upgrading to business versions of Vista: $199, $299, or $399, depending on which edition you choose.

Cost of staying with Windows XP? Apparently priceless.

That's one logical conclusion based on the stories that InformationWeek readers are clicking on fast and furiously these days.Take two of our most popular stories this week (both by Fred Langa): XP's No-Reformat, Nondestructive Total-Rebuild Option, in which Langa shows you how to completely rebuild, repair, or refresh an existing XP installation without losing data or having to reinstall user software, reformat, or otherwise destructively alter the setup; and XP On Your Thumb Drive, in which he offers a step-by-step guide on how to boot XP from an ordinary USB drive.

These stories about an old operating system are no spring chickens themselves: The first was published seven months ago, and the latter a full year ago. Perennial news about what appears might be a perennial operating system.

The XP lovefest doesn't stop there. This week we also published Bill O'Brien's very helpful hands-on piece Make Mine Media: How To Upgrade To Windows Media Center Edition, in which he berates Microsoft for only releasing Windows XP MCE to OEMs-and shows you how to turn your XP PC into a full-fledged media center. XP MCE! You can just hear the crowds chanting.

And the seemly inexhaustible delight that pollsters take in asking CIOs about their Vista upgrade plans continued this week with Deutsche Bank Equity Research surveying IT chiefs about their 2007 plans. The majority (63.6%) said they had absolutely no intention of upgrading to either Vista or Office 2007 in 2007. Only 10 percent definitely say they will upgrade to Vista this year. Sounds like it's XP for dinner again tonight.

What do you think? If you're not thoroughly exhausted from being asked about your Vista plans, give us your opinion below.
