David Daoud ran into trouble when he started using Vista, the new version of Windows that Microsoft Corp. and PC makers have spent millions of dollars advertising since it came out six months ago.
He said it short-circuited key software programs he counts on: Quicken for balancing his checkbook, Lotus Notes e-mail and a networking program that connects his home to the office. His Sony camcorder also doesn't communicate with the PC properly.
Such problems are part of the normal growing pains that come with every major upgrade to the Windows operating system.
To ease those pains, some consumers are seeking out machines equipped with the more compatible Windows XP. That's prompted some PC makers and retailers to give the older operating system more room in their product lines.
