From what i can see, an update to the iMac may well be due soon! As it has been said that apple are waiting for the new 'lower-priced' quadcore processors to put in the new iMacs.

Also the iMac and Mac Mini, are now the only line of computers not to feature NVIDIA graphics, (yes i am aware of the top end iMac's graphics, i mean in general!), and there is speculation, to make sure all the computers in apples line up, have decent graphics!

Do you guys think this is a realistic rumour, and when do you think that the new iMac's, and Mac Mini's will be introduced, i would have thought definately this year!
Also here is a timeline of the iMacs, and you might see, that it looks like the iMacs are overdue for an update!

The only reason i am digging up info, is because i am looking to buy an iMac, and they are quite alot of money, and would rather wait and buy one with quad-core, nVidia GPU and snow leopard! I have got some saving to do though!
