I disagree!
The eMac is an excellent computer for a specific market! People who dont care about technology and just want a computer.
Using the eMac is simple, just plug the power cord, plug the keyboard/mouse and you are set. Everything about that computer is simple and strongly built. There is noway to do something wrong and this is an important factor for computer newbies.
My mom loves her eMac, the display is gorgeous it never failed to her and she trusts it more than any pc she ever had.
For these reason, I see that there is a market for simple computer. It might have shrunk with the mac mini but you have to understand that they both target completely different segments of the market.
eMacs are also very usefull in business office because they are thief resistant, dont cost much/easy to maintain, look nice and are powerfull enough for most tasks.
the real problem with this computer is how similar it is to an iMac, they both have low end video cards and about the same ram limit. I wish they could up the video card in the iMac to something serious and put a G5 in the eMac. It would help to make a distinction between the two, but I dont think its ever going to happen... They will probably keep the eMac long enough for another 1-2 iMac price drop and 0-1 mac mini update. Once the line between product is too blured, they will phase it out. The only chance of survival for the eMac is to difference it from the mini and iMac...
