Computer sales will fare much better than feared but won't get any help from Windows 7, according to revamped estimates from Gartner. The analyst firm had recently predicted a 6 percent drop in shipments for all of 2009 but now believes the numbers will only drop 2 percent compared to 2008. Most of that, however, is attributed to an expected growth in holiday sales instead of any pent-up demand for Microsoft's new OS, which may actually worsen results as PC makers may put too much faith into the upgrade.
