Well, due IMAC line its renewed soon, its tipical you found really low prices on current IMAC models 24" and 20"
I dont think they launch radical changes on new IMAC.
New changes on new IMACS:
NEW ANODIZED METALIC CASE LIKE MACBOOKS PRO
(i prefer plastic white case)
THE NEW CASE ITS SLIMED compared with current case.
New imac no have CHAIN, anyway on current models 24" the chain its ok
New Keyboard designed for IMAC.
IMPROVED WI-FI
(this change really not take a big adventage of wi-fi technology)
Just new Graphic Card NVIDIA
(if you work with 3d, video, card, you really take adventage of this new change or if plain install VISTA for the new games with DirectX 10 support, the new cards support DirectX 10)
The major improvent is, CPU, new imacs come with INTEL SANTAROSA 2.4 ghz or possible better speed.
Anyway that CPU change not is a big improvement compared with core 2 duo 2.33ghz.......
I not think they launch imac cuad core yet...... but can be possible !!
My sugestion is, just pickup new IMAC 24 with 2.33ghz at low price right now
If you plain buy your imac, for sell, after some months of usage...........you should wait for buy the new model launched in 3 weeks.
I really not think, they launch radical CHANGE on imac, ........if they do, i think they prepare more suspense situation, anyway...its apple...................so all its possible !!........but if you check the history of apple anuncements, when they plain introduce radical changes or really new product they make a lot of noise, and this time they saty under normal silence......
