Here are the specs for the low-end PowerMac G5. See my comments next to each item:
Dual 1.8GHz PowerPC G5 (Change from Dual to Single)
900MHz frontside bus/processor
512K L2 cache/processor
256MB DDR400 SDRAM (Change to DDR333 SDRAM)
Expandable to 4GB SDRAM (Change to 2GB SDRAM Max.)
80GB Serial ATA (Change to ATA/133)
8x SuperDrive
Three PCI Slots (Remove the Slots)
NVIDIA GeForce FX 5200 Ultra
64MB DDR video memory
56K internal modem
Guess what? The specs above with my changes are most likely what the TOP of the line new iMac is going to be. I'm not saying I don't wish Apple would do more...I'm just being realistic. Apple is not going to sell ANY iMac that has better features than it's low-end PowerMac G5.
So again, the top of the line iMac G5 is basically going to be the low-end 1.8 GHz PowerMac G5 with a single processor, no slots, and two less memory sockets. That is the BEST we can hope for. Most likely, a 20" screen will be attached to it.
There will definitely be a 17" model that will probably be exactly the same as above with the smaller screen. (Screen size is the only difference between the current 17" and 20" iMac models.)
A 3rd low-end model MIGHT have the 15.2" wide-screen used in PowerBooks, which would allow for resolutions higher than 1024x768, up to 1280x854. (39% more screen real estate.) Otherwise, I'd expect the specs to remain the same as both of the above except a combo drive instead of SuperDrive and possibly a slower 1.6 GHz chip.
Personally, I'd prefer that all models have the same video and include SuperDrive as standard, with ONLY the screen size differentiating the models. But that doesn't sound very Apple to me.
