Microsoft Says 74% Of Business Computers Still Running On Windows XP

74 percent of business PC's are still running on XP, according to Tammi Reller, CVP of Microsoft Windows. That is some measure of how Vista failed to get traction, but also suggests a large opportunity for Windows 7 upgrades.

Reller says the average age of a PC is the highest it's been in a decade at 4.4 years old. Typically that would suggest replacement is imminent, as most enterprise PCs have tended to be replaced every three to five years.

The new wrinkle might be increasing use of smartphones, netbooks or tablet PCs powered by other operating systems. Those devices are unlikely to replacement existing desktops, but might siphone off some of the incremental demand.
