Far from benefiting from an expected boost in sales on the back of Microsoft’s Windows Vista launch, Intel has revealed that it’s even not ready to contribute to the installed base of Vista systems.

Intel’s chief executive Paul Otellini said his company wouldn’t consider upgrading its PCs to Vista until the first service pack has been released, and even then it will hold back on a full roll-out.

"I know of no organisation that is going to adopt it before Service Pack 1 is out - that's in the second half of this year - and that includes us. Starting in the second half of this year we'll do a modest deployment, and continue into next year. That's the large company approach for all the people I've talked to."

Otellini also said he didn’t expect many companies to upgrade their current PCs to Vista, opting instead to hold off on Vista deployment until the time comes to buy a brand-new PC.

"Vista will play out like XP did," Otellini said in reference to Microsoft's last major OS launch. "People won't upgrade the OS on the machine, they will buy it on a new machine when they need to do that.”

However, Otellini said people would warm to the new OS once they play with it. “It's nicer and prettier. For those who use Macs, it's closer to the Mac than we've seen for a long time."
