Incremental improvement seems to be the name of the game for the eMac. The 2004 edition gets a 25% speed boost for both the CPU and the memory bus compared with the 1 GHz 2003 eMac. The G4 CPU used in this model also has a larger level 2 cache (512K vs. 256K), which further improves performance.

The eMac For connectivity, USB 2.0 replaces USB 1.1, the modem now supports v.92, and internal Bluetooth is a build-to-order option. Apple also switched from the Radeon 7500 graphics processor to the Radeon 9200. Additionally, the SuperDrive on the 2004 eMac burns DVDs at 8x, double the performance of last year's 4x drive.

Although it's as compact as the original iMac, the eMac is heavy - 50 pounds vs. 35-38 for the 15" iMacs.

IMPORTANT: The 2004 eMac is covered by the eMac Repair Extension Program for Video and Power Issues, which includes problems with scrambled or distorted video, loss of video, and no power. Apple's website includes a list of serial numbers covered by this program, although refurbished 2004 eMacs may be covered but have a different range of model numbers.
