Just for reference, the first Intel iMac had the following specs:
- Up to 2.0GHz Intel Core Duo
- Mighty Mouse
- 17" and 20"
- ATI Radeon X1600
- iSight Built in
- Front Row and Apple Remote
The new iMac has these specs:
-Up to 2.8 GHz Core 2 Extreme Processor
-Up to 4 GB Memory
-ATI Radeon HD Graphics
-Up to 1 TB Hard Disk
-Wireless 802.11n and Bluetooth 2.0
Last time I checked, 2.8 GHz is more powerful the 2.0 GHz.
Apple isn't going to deck out every product they have, and still price them the way they do. There has to be some difference in between the product lines, other wise people would buy the $500 Mac Mini with the same specs as the $2500 Mac Pro.
If that iMac doesn't suit your needs, quit complaining and buy the Mac Pro.
That is the iMac, nothing is going to change for a while. Even with Rev B, it might not change a whole lot.
