Save your cash...except for the big screen. But that.
There has not been a major update in Mac for quite awhile. I am not talking a speed bump. Yes, the G5 is that, but it sounds like you are not a power user so it might look cool to have that monster of a machine by your desk, but not do much for you that your emac can't do if you mostly do non-power-user stuff.
The best thing is to ask yourself is "what is it specifically that my current eMac *which you say you love* is not able to do that a new G5 or G4 could?
If you cite a long list, then go for a G5 if that will meet your needs. If not, then wait til there is something that meets real needs!
When I upgraded to a new iMac from a five year old one the two reasons I did was OSx and hard drive space. Speed was an issue as well, but I was using a 233 G3 and went to a 1ghz G4...big difference when surfing, mailing, and texting (WP). However, going from an emac G4 to a G5 pro machine won't significantly help emailing, surfing, or texting at all so why do you need a new machine.
I would personally buy a new tv and/or save the cash for the next Big thing from Apple that will change your world. It can't be far off. There is talk of a new form factor iMac that is supposed to be as drastic of a change as this last one was...which was pretty big so who knows what it could be.
Maybe buy a Tivo, get a dish hookup, get high speed acess or an iPod mini or surround sound system which could serve a need that is not being met right now????
Good luck on your decision and let us know what you want to do with the new computer that you can't do now...
