The new iMac, available in 2 sizes only (20" and 24") has been introduced today by Steve jobs during the Mac Special Event. Beside the usual CPU/GPU speed bumps and larger HD, the new iMac features a new enclosure, based on Aluminium and glass. A new keyboard is of course available to perfectly go along with the new style.

On the hardware side, all configurations will feature 1GB RAM, WiFi 802.&&n and Bluetooth 2.0+EDR:
- 20", intel core 2 duo 2 GHz, HD 250 GB, ATI Radeon HD 2400 XT: 1199 euros
- 20", intel core 2 duo 2.4 GHz, HD 320 GB, ATI Radeon HD 2600 Pro: 1499 euros
- 24", intel core 2 duo 2.4 GHz, HD 320 GB, ATI Radeon HD 2600 Pro: 1799 euros
- 24", intel core 2 duo 2.4 GHz, HD 500 GB, ATI Radeon HD 2600 Pro: 2219 euros
The new iMac can sport up to 4GB of RAM (Santa Rosa) and can be powered by Core 2 Duo Merom Extreme clocked at 2.8GHz which is not available before September according to Intel reports... but Apple might have some special deal with Intel, as with the Xeon Quad Core 3.0GHz in the past.
