I think the imacs need the the nvidia chip and a new fresh look
Well, be prepared to be "let down".
The iMac does not need, nor in my opinion will it receive a cosmetic overhaul. As I said previously, Apple like a uniform look across their entire range and the new Unibody Macbook and Macbook Pro range are designed in the same appearance as the Aluminum & Glass iMac.
Don't also forget that the G5 iMac kept it's look as it moved to Intel processors during the transition from PowerPC to Intel.
I know this is Mac
rumors, but people would be wise to let common sense and previous Apple experiences speak for themselves. Of course it could be who is wrong but using previous experience and the aforementioned common sense, I think it's fairly obvious that the iMac update will be a non-event ... literally.
Personally, I'm holding off although I almost bought a 20" entry level iMac for £645 from the Refurb Store two days ago. For me, currently using the original Intel iMac 17" Core Duo model, the step up in spec would have been noticeable, but I am prepared to pay the £800 for a new model should the prices stay the same as they currently are
(that's another topic altogether right there), but I was almost tempted.
I use my Mac mainly for Adobe CS3 programs, mainly Dreamweaver, Flash, and Photoshop as well as watching video files and listening to music via iTunes. Gaming means nothing to me these days since I stepped away from the (now boring in my opinion) gaming scene after owning all three of the current generation systems and selling them on.
My current iMac isn't a slouch when it comes to CS3 but I could use the greater screen real estate and I wouldn't mind if CS3 ran a little quicker and was a little "snappier", so perhaps a Refurb would be a good option. I've set my own deadline for purchasing my new system; March 23rd.
If there's no new systems by then I'll go ahead and buy regardless. If there's new systems available and the speed bump isn't as great as many here have hyped it up to themselves as being, then I'll look at getting an "old" iMac on the Refurb Store.
