I agree with the iMac, too. It's great to use, and it would be better than the eMac for a few reasons:
1) 4:3 CRT screen vs. the iMac's 16:9 LCD
2) G4 vs. the iMac's G5
3) 1.42 GHz vs. 1.8 GHz
If you need more RAM, you can just upgrade. My iMac has only 512 but it runs well. It's rather clear to get the iMac in this writer's decision.
