An anonymous reader writes "Reuters is running a story that Apple has delayed the release of the new iMac until September and has stopped taking orders for the current models."
"We planned to have our next generation iMac ready by the time the inventory of current iMacs runs out in the next few weeks, but our planning was obviously less than perfect."
Quite candid, really.

If your CS lab is forcing you to code in Windows, they're doing something wrong. You should be coding platform-independant C, which you sure as heck won't be getting on Windows (unless you're using a godawful DOS prompt).
What are you talking about? What does developing from the cmd shell have to do with what type of code you can write? You can write code that's just as portable in Windows as pretty much any other platform at the level that portability is reasonably maintainable (i.e. no gui's). Unless you're definition of portable means "*nix" of course.
Plus what the hell difference does it make what platform you're writing in (even notwithstanding the fact that the guys lab is using the same OS that is significantly more likely to land that person a job), the point is to learn how to code. You talk about platform independence, then you start spouting off about restricting the platform (for dubious technical reasons).
FFS. They don't have nine fans to cool the CPUs in the PowerMac. They have nine fans to cool the CPUs quietly. They've designed it the way they have so that, under normal operation, the fans will rotate at a fraction of their full speed, meaning that they are that much quieter than normal.
If you look at this PDF file, you'll see that typical power dissipation of the 1.8 GHz G5 is 42 watts. Assuming that's 75% of the maximum, we still end up with a maximum power rating of 56 watts. In comparison, typical power dissipation of an AMD Barton running at 1.8 GHz is around 54 watts typical, 68 watts maximum; an Intel P4 at 2.8 GHz (the slowest I can find readily available where I live) is rated at 56-68 watts (same page).
The other thing to bear in mind is: that thermal rating for the 970 is based upon figures for the 130 nm process. The die shrink to 90 nm should reduce it.
I don't think cooling is a major problem. It may take a bit of engineering work, but there's nothing particularly hard, I'd imagine. Yes, it's more than they've had to deal with when using the G4, but at least they don't have power constraints (which they will when it comes time to slide the G5 into a PowerBook.)
They say as much in their statement:
