I was reading apple's 10-K filed yesterday and I stumbled across this:
<QUOTE>Total unit sales of desktop systems fell 15% during 2003 compared to 2002. iMac systems unit sales declined 16% from 2003 to 2002 resultingfrom a shift in sales away from desktop systems in favor of portables. Also, the current flat panel iMac form factor was in the eighth quarter of its life cycle by the end of 2003 and did not experience significant enhancements until the release of the 20-inch flat-panel iMac in November 2003.</QUOTE>
Sounds like even apple themselves think the imac form factor is due for an overhaul!
