Businessweek has their take on the new flat-paneled iMac... though they seem to have some more real sources...
What gives the iMac its slick appearance is a 15-inch screen with a resolution of 1024 x 768, say those who have seen the prototype. They say the redesign now resembles Apple's Studio Display flat screen -- but with a pudgy rear end, which holds the computing components. And thanks to a DVD drive and ports for peripherals, it's also a tad thicker than the Studio Display around the middle.
The article includes further specs including a G3 up to 1 ghz, GeForce2 MX, OS X as default, and described as "nothing short of spectacular."
