One more G4 iMac and THEN G5?
A lot of these complaints--about price, size, cooling, and shape, are based on the G5 assumption. I'm encouraged that MacRumors says thats likely!
But Apple did recently say that iMacs share a similar problem to PowerBooks in terms of fitting a G5 plus cooling. Now, it wasn't worded AS directly as the PowerBook comment, so there's always hope, but it did sound like the next iMac MAY WELL BE A G4. Which is fine... IF the resulting performance is still offered at the right price!
G5 iMac rumors might be true BUT still a ways off. I'm sure Apple would prefer to update the form factor and the CPU together, though, in which case the next iMac might even be the "old" shape too.
So be ready for the chance that the current iMac may get one more speed bump (and hopefully price drop), and that WWDC will be all about Tiger--and THEN the new G5 iMacs will follow in August or Sept. or whatever.
No Apple doesn't "want" to do that--but they deal with reality and we can't be sure the G5 iMac is possible yet.
But a hypothetical low-end (headless?) Mac might still come sooner than that as a NEW model--a G4 of course, if it's low-end.
(Also--when I imagine the display being optional and attaching to a slim CPU via an arm... I meant when the CPU is sideways as in horizontal... in other words, not much different from current Macs if used in that way.)
