There is something lacking in even the latest eMac...Doesn't OS X run only moderately well with 256mb of ram?
As I understand it, economy macs have never been meant for expansion...that's what buying a whole new power mac is for. Also, the economy field can and does consist mostly of the casual, non-professional user, right? Let's say that's a given. In the education market, gaming clearly isn't a priority function, and for most purposes, their 32mb card should do just fine. Next question: Do gamers fall into the category of casual, non-professional users? If you find that it is a general yes, then you might question just how applicable the eMacs seem to be, in one of their competitors' fields. Not much gaming capacity; they absolutely have to stick to education. Now let's look at Dell.
Let's say you got a dell box for $499, with integrated graphics and a processor which is easily fast enough to handle just about anything on the market, in both gaming and education. If the integrated graphics can't handle certain things, you could still upgrade it rather easily. Since these economy dells usually have free AGP slots, one can easily buy a basic, ~$50 GeForce FX 5200 card, and be able to handle almost everything available, both now and some time later. Not so with an eMac!
Custom built is even better; a gamer can spend very little cash while getting the benefit of increased personal knowledge of the internals of their computer (if they do it themselves), and they can have everything done their way. Apple has made this entirely impossible. Another special benefit to a self-built computer is, the components very likely won't start breaking within the first year, unlike the economy dell. But what edu would buy Custom built computers!?
Macs are not for gamers; so why does anyone even make games for them? Side-interest only. I don't know of very many people who would buy a mac just to play games. To get a mac capable of handling newer games, one must put out 2-4x what they would otherwise have to pay for a far superior gaming pc. What are they paying for later by initially paying so much more? Why, they're paying extra because they won't spend as much on games, of course, since there aren't 1/10th the number of games available for mac.
And who wants to spend $2,000 on a gaming system, especially one that doesn't even include a monitor?
Mac has no gaming system that is not also a high level, high cost work machine. As for the eMac...Fortunately the e has always stood for Education, because that's what field it belongs in.
