Apple Computer plans to serve up a new iMac model with a larger flat-panel display during next week’s Macworld Expo trade show, according to sources.

The upgrade to a 17-inch liquid crystal display (LCD) comes as sales have all but stalled on existing 15-inch flat-panel iMacs. Apple unveiled the original flat-panel iMac, which suspends the monitor from a pivoting arm attached to a hemispherical base, during January’s Macworld Expo in San Francisco.

The tech market really has stalled… but if it gets me a 17 inch monitor on an iMac, I can live with that.
